Cartography is most certainly a very different task than data analysis and I think that tools like InkScape are a very important part of the toolbox.

To promote fosGIS or promote Open Source. I was under the impression it was the former and so I suggested not using Inkscape. I presumed, the Atlas would illustrate what most mere mortals could do with fosGIS rather than show what some creative genius can achieve.

If you have any opinions on this matter PLEASE speak up -- don't just sit in the background as *Cameron will take the lack of any responses as an implicit YES to his proposal*. Personally I have a problem with Project Overviews, or any technical documentation for that matter, being locked up in Commercial-in-Confidence derivatives. I think Project Overviews, which can be legitimately be included 'as is' in a proposal or design document, shouldn't need to be reworked. To me the reworked document, which needs to include your name as original author, implies some sort of collaboration has occurred when none has occurred. Yes, reworked documents do look better but contribute nothing the the broader CC/FOSS/OSGeo community. But this is my opinion.

Re: [Live-demo] Re: [OSGeo-Discuss] Re: [Gvsig_english] New site demonstrating the use of Free Open Source Software
Helena, Thanks for the comments. I have included some feedback regarding particular points below. On 30/04/11 11:53, Helena Mitasova wrote: I have prepared this data set because I thought that it would be useful to have a set of simple data sets for different regions with standardized names of data layers so that we can use the same tutorial with data sets from different regions. I understand the concept but if you did this you would need to standardise the field names also. So Simon, if you are going to create a data set for Australia to go with your tutorials, it would be great if you could use the same names as in our basic data set (or if you have a suggestion for a different name, please let me know - at this stage it will be easy to change it on our side). I have already acquired some local data. You can see what is provided at http://gis.fossworkflowguides.com/#data. Then we can use your tutorial with our nc data set and students/users in Australia can use our tutorials with your data set. We can have this for many countries and many different software packages we just need to agree on the names for data layers. I can see the logic here. Standard file names. Standard attribute names. Various formats. Various regional datasets. How do you propose to store different languages? This would intrinsically change both the file and field names. When I considered localisation and translation of my tutorials, I though that most people would just recreate the images and rejig the text accordingly - using the existing file as a predominantly completed template. There are certain tasks that are region specific, such as the coordinate systems, but many tasks, from display to analysis, would be the same. With this in mind, putting aside regional aspects, having one dataset that most people use in things like the LiveDVD provides for a consistent experience. My only issue here is the use of low resolution continent-wide data in the quickstarts and tutorials, when most people would be working at a regional or local level. Regional aspects is an interesting issue that need further consideration. Apart from distinct CRS, local files have distinct names, fields of attribute tables have distinct names, data has varying accuracy and/or currency, etcetera. These variations make working with regional datasets unique and tutorials that demonstrate the use of 'raw' files -- as you would expect to get them if you went and purchased them from a regional authority -- valuable and enlightening. With this in mind I must confess I am in two minds with trying to standardise all data. When considering creating a tutorial series I wanted to provide a resource for all people to use regardless of the country. In my mind this only required me to provide the data used to create the tutorials so others could repeat the steps -- which I did -- and ensure that colloquial terms are adequately explained. Derivative creation is another issue intrinsically bound to this issue. Apart from slight variation in text (assuming you are not translating the document) all the images need to be redone to show the local data in context. If you are going to go through all this effort changing a few names is a minor issue. The way I have handled this in my tutorials is to tag file names and other elements with unique tags. This provides the ability to substitute elements of the HTML webpage based on a simple translation table and substitution routine. In theory, it would be a simple matter stating that when using this vector file the term altitude should be replaced with elevation. My experience has show that the biggest impediment to derivative creation is the ability to disarticulate a tutorial, modify those elements that need changing and put it back together quickly -- as explained in detail on my website, this is why I fell back to HTML. Ideally, we should have a Content Management System that stored educational material at high enough resolution to manage this disarticulation quickly and efficiently; but, alas one does not exist at present and it is necessary to hobble together an alternative. So in summary, I can't see the value of modifying the current data I have to make a consistent dataset, as creation of a derivative using the North Carolina dataset will require recreation of the 30-40 images shown in a tutorial anyway, and a simple search-and-replace of a dataset name or field name would be a minor additional task. -- Cheers Simon Simon Cropper Principal Consultant Botanicus Australia Pty Ltd PO Box 160, Sunshine, VIC W: www.botanicusaustralia.com.au ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

The first project that sits down and defines how submit word, pdf, html, rst, odf etc... (with manual steps if needed) will have a much greater chance of success. Perhaps that project will be yours? I agree. I have resisted finalising my tutorial on 'preparing tutorials' so I can iron out any nuances before asking others to follow the same procedure.

Hi, I apologise in advance if you have received this email more than once because you are listed on two or more mail lists. I would like to announce the launch of a new website called http://www.fossworkflowguides.com that may be of interest to you. The site's aim is to provide detailed workflow guides using free and open source software. The target audience is beginners to intermediate users. The ultimate aim is to get more people using foss in their businesses. These are not manuals but rather guides on how to get complex tasks sequences or workflows completed using free and open source software. The website is the main medium by which information is being disseminated. That said, PDF files have also been provided that can be downloaded and referred to when the Internet is not available. Of particular note for this group is the 'fosGIS Workflow Guide - A guide to the use of FOSS to view, edit, create, analyse and map geospatial data (http://gis.fossworkflowguides.com)', although if you look at the main page you will see I also intent to publish tutorials on use of bash and python (http://scripting.fossworkflowguides.com). Other guides are planned but will depend on how enthusiastically the currently published and proposed tutorials are received. An initial instalment of tutorials have been posted along with copious support documentation and CC-BY-SA Data. I welcome any feedback. You can post back to this mail list (if you want to have a debate) or use the feedback form on the website http://www.fossworkflowguides.com/#feedback, if you want to just point out a typo or suggest a topic for a tutorial. The current list of tutorials are... - Installing gvSIG 1.10 on Ubuntu 10.04 LTS - Installing gvSIG 1.10 on Windows XP - The basic configuration of gvSIG for normal use - Datums and Coordinate Systems used in South-eastern Australia - How gvSIG handles Coordinate Reference Systems If you want to be informed of the publication of other tutorials in the future register for email alerts at http://www.fossworkflowguides.com/#alerts. -- Cheers Simon Simon Cropper Principal Consultant Botanicus Australia Pty Ltd PO Box 160, Sunshine, VIC W: www.botanicusaustralia.com.au ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

I have created a DXF showing the lots in a hypothetical subdivision by back-engineering a shapefile but the final result is not as I would normally receive the data from a surveyor. I was wondering if someone could import the file created and manipulate the colours of the layers so they present as one would normally expect to see the layers (lines and annotations) - at the moment the polygons are at the forefront and the line work is all one colour. If you are particularly enthusiastic you can import the contour data or superimpose some hypothetical features of your own (sewerage, road infrastructure, paths, etc). Anyone interested can contact me off list. The final file will be made available under the CC-BY-SA Australia 3.0 license. Any assistance will be appropriately credited. -- Cheers Simon Simon Cropper Principal Consultant Botanicus Australia Pty Ltd PO Box 160, Sunshine, VIC W: www.botanicusaustralia.com.au ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
[OSGeo-Discuss] LiveDVD Copyright Ambiguity
Hi All, I would like ask the question about copyright associated with the Live DVD produced by LisaSoft and OSGeo. I have been looking over the website and note that the copyright is attributed to LisaSoft and/or OSGeo. If you work you way down to the html versions of the quickstart guides they are also copyrighted to OSGeo. If you work your way back to the RST source files for these pages you can see that the authors released their work under a 'Creative Commons' license. Take the MapGuide as an example... https://svn.osgeo.org/osgeo/livedvd/gisvm/trunk/doc/en/quickstart/mapguide_quickstart.rst http://live.osgeo.org/quickstart/mapguide_quickstart.html Shouldn't the website be 'Creative Commons', or at least the quickstart section? At least this is my understanding of the use of CC works. Also, I note that most authors of rst files simple inserted 'Creative Commons' under the license section. If you go to the CC site there is no license specifically called Creative Commons'. http://creativecommons.org/licenses/ The license relevant to this work should be unambiguous and works should point to the specific deed relevant to the license that they are releasing the work under. 'Creative Commons' is not specific enough. I know this is a old topic that has been debated before but I would have thought that these issues would have been clarified by now - especially as the DVD is in its 4th rebirth. For debate, I have included the following clause extracted from the FAQ webpage on the Creative Commons Site http://wiki.creativecommons.org/FAQ Note I have inserted ### comments ### throughout... You will notice that none of the ways proposed here to 'properly attribute a Creative Commons licensed work' have been met. As a group OSGeo should be aspiring to ensure any new works *at least* have unambiguous licensing both for the original works and the Live DVD. *** start quote *** How do I properly attribute a Creative Commons licensed work? All current CC licenses require that you attribute the original author(s) ### not done in final product ###. If the copyright holder has not specified any particular way to attribute them, this does not mean that you do not have to give attribution. It simply means that you will have to give attribution to the best of your ability with the information you do have. Generally speaking, this implies five things: * If the work itself contains any copyright notices placed there by the copyright holder, you must leave those notices intact, or reproduce them in a way that is reasonable to the medium in which you are re-publishing the work ### authorship and license placed in RST files not maintained in HTML ### * Cite the author's name, screen name, user identification, etc. If you are publishing on the Internet, it is nice to link that name to the person's profile page, if such a page exists ### not done ### * Cite the work's title or name, if such a thing exists. If you are publishing on the Internet, it is nice to link the name or title directly to the original work ### not done, list of contributors not linked back to contributions, also contributors section hidden under sponsorships page ### * Cite the specific CC license the work is under. If you are publishing on the Internet, it is nice if the license citation links to the license on the CC website. ### not done, in fact I could not find any mention of CC on the LiveDVD webpage ### * If you are making a derivative work or adaptation, in addition to the above, you need to identify that your work is a derivative work i.e., “This is a Finnish translation of the [original work] by [author].” or “Screenplay based on [original work] by [author].” ### not done ### In the case where a copyright holder does choose to specify the manner of attribution, in addition to the requirement of leaving intact existing copyright notices, they are only able to require certain things. Namely: * They may require that you attribute the work to a certain name, pseudonym or even an organization of some sort. ### not done ### * They may require you to associate/provide a certain URL (web address) for the work. ### not done ### If you are interested to see what an actual license (legalcode) has to say about attribution, you can use the CC Attribution 3.0 Unported license as an example. Please note that this is only an example, and you should always read the appropriate section of the specific license in question ... usually, but perhaps not always, section 4(b) or 4(c): http://creativecommons.org/licenses/by/3.0/legalcode *** end quote *** -- Cheers Simon Simon Cropper Principal Consultant Botanicus Australia Pty Ltd PO Box 160, Sunshine, VIC W: www.botanicusaustralia.com.au ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman

For this reason several persons (at least myself) submitted their works and could afford the costs of the conference (my director approved the cost saying, well if you will have a publication is ok..). After more then one year, Thierry Badard, the person that take in charge the task to find the editor for the papers do not produced anything.

Please, stand out! Hi Mateusz, all, [I cc discuss list to broaden the audience] thanks for encouraging the participation of women in OSGeo! Lot of thoughts and live discussions took place at the conference, and I had a chat with Helena about her perception of gender bias. In the US, she feels that women are no more a minority in the computer science field. It is not the same in other parts of the world, however, and that's something that OSGeo, as US-based foundation, has to consider. Athina and me also discussed about how women presence is uneven regarding the profile, i.e. coders, managers, sysadmins etc, so it is risky to generalise. Lots of women attended the conference, and honestly I didn't expect it, so it was a very pleasant surprise :) I'd be interested in the women percentage in workshops, presentations, guests, and so on, and of course, in direct feedback from them. That said, I join Mateusz and Athina in encouraging all women to show up :) Best regards, best regards Anne Hi All, Personally I find such conversations quite frustrating and irritating. The whole tenor of the conversation smacks of political correctness gone mad. Is there any evidence that women have been specifically targeted by OSGeo so that they can not make it to the board? Is there any evidence that women are unable to attend or contribute to OSGeo activities? No, at least from what I have seen. That fact that the author of this email, who appears to be a woman, has indicated that there was plenty of other women present at the conference seems to fly in the face of general observations that women are not some how able to participate in the organisation's activities. The fact that a woman has not made it to the board has more to do with no one with suitable experience being nominated! Not some malicious anti-woman campaign by the male-dominated OSGeo Community to exclude women! Come on people, come back to reality and focus on what OSGeo is about (if you are unsure what the foundations goals are look at the webpage http://www.osgeo.org/content/foundation/about.html). Having carefully looked at the foundation's goals I was unable to see any comment on excluding any particular group of people, gender-based or otherwise. -- Cheers Simon Simon Cropper Botanicus Australia Pty Ltd PO Box 160 Sunshine 3020 P: 03 9311 5822.

[OSGeo-Discuss] Anyone know of a FOSS GIS solution to creating terrain profiles from contours lines or an elevation raster (DEM)?
Hi, I want to create a terrain profile along a particular transect for a project I am working on. I have contours and have created a raster file showing elevation data. I was wondering if someone knew of a program that I could visualise the contour data, draw a line over this, and have a 'plan' view of the profile created. I want to show the profile of two types of creek systems in a area I am working -- one is a broad (200-300m) 'U' shaped creek bed, while the other an ephemeral creek that has hardly made a scratch on the terrain (1-10m width). I could print the map with a scale, use a ruler and transfer the data to a graph paper -- but we are over this aren't we? I retired my colour pencils, scale rulers, spline, curves, compasses, etcetera years ago! I have searched actively and looked at gvSIG, OpenJUMP, SAGA, Sextante, QGIS but nothing is obvious. SAGA looks promising but it requires a 'grid based DEM'. Is this simply an issue of trying to use one tool (GIS) to do everything, and really I should be looking at other tools (CAD). If so can someone point me to a FOSS solution. -- Cheer Simon Simon Cropper Botanicus Australia Pty Ltd PO Box 160 Sunshine 3020 P: 03 9311 5822.

Re: [OSGeo-Discuss] Auto-cataloging of image files
Tyler, gdaltindex did not work. The Windows EXE does not like 'wildcards' and does not recognize ECWs. Your python program looks promising as a catalog of datasets in a directory but does not create a spatial representation of this information, which is what I need. Additional functionality worth considering is the ability feed the routine OSGeo Project Files for the various open source GIS packages and have the datasets used extracted and used to create a project catalog with all the relevant metadata. The users could also be allowed to augment certain fields. A utility like this would be good to reference what vector and data was used in a project when the information is still on the system. If you are like me, I am bound by Data Supply Agreements, which require me to remove the data from my computer once the project is finished. Prior to deletion it would be great to get as much information on what was used as possible. Cheers Simon Simon Cropper Botanicus Australia Pty Ltd PO Box 160, Sunshine, Victoria 3020. P: 9311 5822.

Re: [OSGeo-Discuss] Re: Will there be an OSGeo Desktop shootout atFOSS4G 2010?
I agree with Stefan. I have found comparison tables of little use as the compiler has to summarize what is probably quite complex routines. They rarely give a potential user like myself the complete picture. My view has been that the only way to evaluate the usefulness of a program is to use it on actual data trying to do actual things. I have tried multiple OS GIS packages and they all do different things in different ways. Some useful some novel (to me). What really counts is if you can use one program to complete your normal workflow without needing to use other packages. I am not saying that someone should not use multiple packages during their normal work week only that you should be able to do your normal work without having to transfer data (and half the time actually convert data) between various packages to get what you need done. So from my point of view projects should not look at other projects, developers should not list functionality of their program or any other combination. Users should provide standard workflow tasks -- repetitive tasks sequences they complete regularly. Then be asked to complete those tasks on each of the programs being tested. Then the users rate ease of setup, ease of use, suitability of output, support, etc. The actual list of user experience ratings can be knocked up by an overview committee. This committee could also vet the users who put their hand up to ensure a good spectrum of users and tasks, from different sections of society (academic, commercial, newbie) are all represented and no bias exists. If developers think this might be too harsh (as users may not fully understand what is going on or how the program works), maybe a middle ground would be that the developers submit a solution to these workflow processes. The users follow these instructions and evaluate the outcome. This avoids users baulking at some quite eccentric GUI interfaces or program setup (solution must provide clear setup instructions for Windows and Linux). These solutions are tried and reviewed by the user. The workflows, results, comments and developer solutions can be collated onto one site (the OSGeo site seems appropriate) as a valuable resource for developers and user alike.

I think Pauls idea sounds interesting - because this whole comparison thing is a) quite cumbersome when we have 10 desktop GIS (+ X), and b) neither really worth because desktop GIS are used for a multitude of tasks, while web map Servers or databases aren't that much - right? So as Paul is quoted on the osgeo wiki: one needs to set up use cases first (just wrote that today in a new article too, which contains a section on selecting free GIS software). And I also discovered that just most of the projects have a different focus during my evaluation. Which of course does not mean that such thing should not be presented - but it must be focussed in some way or the other to have a benefit. And as a side note, I am not sure if measuring processing times makes sense either, as GIS analysis feature sets are so different. However, I am in for testing with OpenJUMP. Two more notes: - my comparison tables are now already 2 years old now (from 2007), i.e. need some update (but the last pub in Ecological Informatics took into account newer developments too, but is superficial and focused towards the "average" GIS users). - I gave a talk about this at OGRS: http://www.ogrs2009.org/doku.php?id=keynotes pdf can be downloaded from there. cheers from Germany right now (Xmas) stefan PS: I know also of this comparison by T.

[OSGeo-Discuss] Quick hello and request for assistance finding Open Source
Hi Everyone, My name is Simon and I am an environmental consultant. I use a variety of open source GIS systems and tools almost every day to analyse flora, fauna and vegetation data. I am interested in OSGeo both from the standpoint (or my underlying belief) that software and data should be free (you know how the mantra goes) and my desire to contribute to a broader community effort to develop appropriate software for users. I have been actively using OpenJUMP, Kosmo, OpenEV, EveryDWG and Sextante. I have tinkered with Ilwis, GRASS, Quantum (various versions) and a few others I have lost track of. I am currently using GVSIG+Sextante, which I find very useful and easy to use. I am an old user of ArcView 3.1+(numerous scripts/extensions). I have a common GIS problem but can not find any OSGeo project that has provided a set of tools to combat it. I need to establish the distance+angle between various geometries (points, lines, polygons) in same layer and in different layers. A specific problem I currently have is finding the minimum distance and angle between 200 odd polygons in the same layer. Each polygon has a unique id and I want to get a table with UID_A, UID_B, MINIMUM_DISTANCE, ANGLE. I know that ArcGIS and ArcView have this functionality, and script exist for old versions of ArcView, but I am looking for an Open Source alternative. Ideally such a tool would create the following data for each geometry type... POINTS -- UID_A, UID_B, DISTANCE, ANGLE LINES -- UID_A, UID_B, DISTANCE_AT_CLOSEST _POINT POLYGON -- UID_A, UID_B, MIN_DISTANCE, MAX_DISTANCE, HAUSDORFF_DISTANCE, CENTROID_DISTANCE, ANGLE_BETWEEN_CENTROIDS What I have found already... I have noted that Sextante can create a matrix of distances between points within the same layer. With rows and column representing the complete set of points being compared. I have also found QGIS has a fTools Plugin that allows you to "Measure distances between two point layers, and output results as a) Square distance matrix, b) Linear distance matrix, or c) Summary of distances."

Re: [OSGeo-Discuss] Quick hello and request for assistance finding Open Source
Peter others,
With PostGIS what is the best option for installation to trial this
option. Where would you enter the SQL query?
If you go to the PostGIS page it pushes you to UDig. Does UDig have the
functionality to send SQL statements to the database? Does PostGIS
install if I install UDig or should I install in a set sequence, a bit
like Giovanni suggested for Grass.
Dumb question - "Is PostGIS-UDig" setup to operate as a desktop type
system? Everytime I looked at UDig I got the impression it used web
resources and was geared to enterprise solutions to multiple users to a
online-resource repository.
Alternatively is anyone aware whether gvSIG can query the database in
this way with beantools or Jython? If so, how? I know gvSIG can connect
to PostGIS?

Simon, you could do this as a PostGIS query. To take the
polygon case, if you loaded the data into a table in PostGIS called
parcel (say), you could run a query something like the following (not
guaranteeing this is exactly correct but something along these lines):
select a.id, b.id,
ST_distance(a.geom, b.geom),
ST_distance(ST_centroid(a.geom), ST_centroid(b.geom)),
ST_azimuth(ST_centroid(a.geom), ST_centroid(b.geom))
from parcel a, parcel b
This would give you ids, shortest distance, distance between
centroids and angle between centroids. There are no doubt others here
who can correct my SQL syntax :) !
There is a simple utility to load a shape file into PostGIS.

Hi Everyone,
My name is Simon and I am an environmental consultant. I use a variety
of open source GIS systems and tools almost every day to analyse flora,
fauna and vegetation data. I am interested in OSGeo both from the
standpoint (or my underlying belief) that software and data should be
free (you know how the mantra goes) and my desire to contribute to a
broader community effort to develop appropriate software for users. I
have been actively using OpenJUMP, Kosmo, OpenEV, EveryDWG and
Sextante. I have tinkered with Ilwis, GRASS, Quantum (various versions)
and a few others I have lost track of. I am currently using
GVSIG+Sextante, which I find very useful and easy to use. I am an old
user of ArcView 3.1+(numerous scripts/extensions).
I have a common GIS problem but can not find any OSGeo project that has
provided a set of tools to combat it. I need to establish the
distance+angle between various geometries (points, lines, polygons) in
same layer and in different layers. A specific problem I currently have
is finding the minimum distance and angle between 200 odd polygons in
the same layer. Each polygon has a unique id and I want to get a table
with UID_A, UID_B, MINIMUM_DISTANCE, ANGLE. I know that ArcGIS and
ArcView have this functionality, and script exist for old versions of
ArcView, but I am looking for an Open Source alternative.
Ideally such a tool would create the following data for each geometry
type...
POINTS -- UID_A, UID_B, DISTANCE, ANGLE
LINES -- UID_A, UID_B, DISTANCE_AT_CLOSEST _POINT
POLYGON -- UID_A, UID_B, MIN_DISTANCE, MAX_DISTANCE,
HAUSDORFF_DISTANCE, CENTROID_DISTANCE, ANGLE_BETWEEN_CENTROIDS
What I have found already...
I have noted that Sextante can create a matrix of distances
between points within the same layer. With rows and column representing
the complete set of points being compared.
I have also found QGIS has a fTools Plugin that allows you to
"Measure distances between two point layers, and output results as a)
Square distance matrix, b) Linear distance matrix, or c) Summary of
distances." QGIS 2009.
I suspect that GRASS would provide this functionality but

Re: [OSGeo-Discuss] Quick hello and request for assistance finding Open Source
Peter,
Tried loading PostGIS 8.4 crashed because no Postresaql.
Tried loading Postressql then PostGIS - this worked but no "simple
utility to load a shape file into PostGIS" could be found.
I found a SQL dialog box in the pgAdmin (GUI) but I found nothing but
HTML links in the PostGIS directory. How is this utility started. It
appears to be a driver for PostgreSQL, not a software utility. If this
is the case the GUI for the pgAdmin does not have a utility or tools
that imports shapefiles. The manual takes of running certain programs
but it example appears to be using demonstrating the terminal in linux.
Do you run some command line program in the command prompt?

Re: [OSGeo-Discuss] Quick hello and request for assistance finding Open Source
Peter,
Sort of answered my own question. Found the EXE in the binary directory
of PostgreSQL.
Tried to get the program to work but I could not get the file to import
the shapefile into a database. I will need to spend more time working
on coming to grips with PostgreGIS, PostGIS and others components. This
option is not a 'quick fix' rather 'a alternative way of thinking' --
resulting in a high learning curve as I have to master each individual
component and the nuances of how the 2-3 utilities interact. Thanks
anyway.

Re: [OSGeo-Discuss] Quick hello and request for assistance finding Open Source
Giovanni, I installed the QGIS + GRASS + PLUGIN as you suggested using the OSGeo4W installer. I can only use Grass Tools IF the layers are grass layers imported into a new map set. I do this but v.distance does not allow me to select the "From" vector file so the routine baulks. I am either (a) importing the shapefiles wrong, or (b) the development version of QGIS is not fully integrated with Grass Tools. I presumed that by going through QGIS I would be able manipulate the shapefiles directly. The problem with this option is to do simple vector queries requires a complete new GIS setup, two distinct programs (QGIS + GRASS) running, the need to convert shapefiles to grass format (the preference would be the ability to manipulate shapefiles natively) and the move project files to a central repository. What I will try is to run WinGrass again to cut out the middleman (in this case QGIS). Maybe it will work this time. tick, tick, tick... OK, I have installed WinGrass again. Since I created a mapset using QGIS the program opened once I pointed it to the default map location. Looking in more detail at v.distance I note it "Find(s) the nearest element in vector 'to' for elements in vector 'from'". Not what I needed. I need the distance of every feature from every other feature. That aside I find the routines are infinitely prescriptive - I presume you would be able to made the wizards choose defaults that could be changed by a user. As it is, it assumes you want to pick everything so it is a tedious task to figure out what needs to be done just to get one minor task completed. I spent about 40 minutes trying to select the various options to get this one routine to work - yes, I did read the manual. Eventually I gave up. Grass promises to provide immense power but in the absence of a easy to use GUI interface make it extremely difficult to utilize. I was hoping for the workflow... VECTOR1 + VECTOR2 == new tool, simple command line or GUI interface, one button == TABLE As its turning out with this option and the PostgreSQL option... (VECTOR1 = NEWVECTOR1) + (VECTOR2 = NEWVECTOR2) == new tool, complex, finicky, multiple processes == PROPRIETY TABLE == TABLE (if you are persistent). Giovanni, thanks for the tip of where to look. I'll keep playing with Grass but I don't think it will solve any of my short term needs as I don't have large amounts of time available to master this system (same problem with PostgreSQL). As it is I have already spent 5 hours trying to get the various options proposed to work - what is frustrating is that neither did.
