RE: [OSGeo-Discuss] Acid Maps demo
Just a quick question...What browser is this optimized for? IE7 (my work browser dictated by our IT dept) does nothing except put up 3 buttons for isoline, voroni and heatmap. No image ever comes up.

RE: [OSGeo-Discuss] help with geotifcp usage
It's been a bit since I scripted anything in bash and I don't have anything
fired up at the moment. You'll have to fill in the details on the scripting but
something like this should be close to working
#
FILES = /path/to/files/*.tif
For f in $FILES
Do
Echo Processing $f...
Geotifcp -g a.tif ${f%.*} ${f%.*}.newtif
Done
Once the processing is done delete the *.tif and then mv the *.newtif to *.tif.
These steps could be handled inside the do but for a one-off process a little
manual review of results before a delete works well for me.
Just a random thought

Hmm, the help file doesn't say much does it. Did you try using a thrid
file name on the end instead of b.tif (again)?
Seems like the following works
geotifcp -g a.tif b.tif c.tif
creating an extra file c.tif. What a shame. Now, to figure out if I
can apply this blessed proj info to 100 files in one shot or not, and
then delete 100 old files.
Also, I wish these darned commands were named consistently. When I see
`geotifcp` I think of its analog as `geotifls`, and when I see
`listgeo` I think of its analog as `copygeo`. What a shame its not so.

A little more on geotifcp. It doesn't really have an explicit
usage/help switch, but if I type just the command, I get the usage
description. There is a typo in it, however
$geotifcp
usage: gtiffcp [options] input... output
huh! What the heck is `gtiffcp` ?
$gtiffcp
-bash: gtiffcp: command not found

RE: [OSGeo-Discuss] Data format frustration - too general!
Good Morning berryman, Google 'gis traffic analysis' for some possible answers Your message really has 2 parts as I see it so I'll give a shot towards each. First: You might want to start by rereading the manuals for your GIS software package in use and other GIS references specifically areas on projections. Your 'unitless locations' statement suggests to me a big hole is your knowledge. It's only unitless because you have not defined the units in the software or do not know the units of the source data that you are working from. GIS software packages typically support many different projections and once a dataset's projection is defined reprojection can occur with ease. Everything has some level of error and a projection is a way of managing that error. Just as an example, a quick check of my ESRI ArcGIS installation lists 4000+ different predefined projections. I don't know how many are defined in OSGeo. Then, because it might be relevant to your project, you have surveyor defined coordinate systems that you might come across working with traffic alignments. These can be problematic because they might not be able to be converted easily. I'm curious how you are going about doing the encoding. Are you using road construction plans or aerial imagery for your base or something else? Without knowing the established projection of your source data and how different data sets interrelate then moving forward will be impossible because you cannot correlate something like vehicle stopping distance to your generated data. Living in the US and working for a local government, I do 99% of my work in either a State Plane or UTM projection. It's much easier to do length/area calcs under these conditions than with Lat/Long but I can export to LL with a few clicks of the mouse provided the software knows my starting projection. Second: For my personal opinion, any piece of software can be considered a GIS if it allows the spatial relevance of 2 or more objects/entities to be evaluated. This covers a map of land ownership, your traffic analysis and the screen my dentist brings up that shows graphically where all my fillings are. That being said, are you attempting to utilize 'GIS software' in place of a commercial analysis package due to cost? If so then you are definitely taking the 'hard road' because decisions such as database format and other analytical constants will have to be made by you and the engineer certifying the results not to mention so custom software development will possibly have to occur. It is very common to have one database for the spatial features and another for the analytical features with a field or 2 that link them together. Looking at the larger picture, 10% of the project will be the line work. 90% will be the data/intelligence applied to the line work.

Hello, I am hope to use GIS for a traffic analysis program that I am involved with. After having looked at a couple weeks worth of GIS resources, I still feel like I haven't found what I'm looking for and it's time to get some human input. The main source of my frustration is that all of the standard data formats seem to be too general for my purpose. Common formats provide the ability to encode points, lines, polylines, and polygons (where the locations are unitless). But I need the ability to encode the geographic location (e.g. lat/long, NAD83) of high-level constructs. For instance, I'm not just interested in the location of streets, I'm interested in the location of each lane. I also need to know how street topology and traffic direction so that I can make path planning determinations. Finally, it would even be ideal if I could encode the location of traffic signals, stop signs, bus-only lanes, etc. I know that these types of encoding must exist somewhere , because my Garmin GPS understands the rules of the streets and can anticipate things coming up. For instance, it might tell me stay in the right lane. Are there standard data formats for encoding this information? Or is the ability to encode this a non-public extension of some more generic standard? If so, then how do I go about extending some other standard for my application?

RE: [OSGeo-Discuss] OSGeo maintained ArcSDE (EDN ?) instance
Check with your ESRI sales rep. It's fairly easy to get 30-90 day demo copies of their software. This also presupposes that a test instance of your flavor of SQL can be installed somewhere for ArcSDE to sit on top of along with the necessary hardware. Tom -Original Message- From: discuss-boun...@lists.osgeo.org [mailto:discuss-boun...@lists.osgeo.org] On Behalf Of Yves Moisan Sent: Thursday, February 11, 2010 1:35 PM To: discuss Subject: [OSGeo-Discuss] OSGeo maintained ArcSDE (EDN ?) instance Hi All, I know the subject line doesn't exactly sound like an appropriate topic to discuss on the OSGeo list, but I'd like to make a suggestion to see if there is any traction to it or not. I -- and I'm sure quite a few FOSS4G users on this list -- sometimes have to deploy FOSS4G solutions on corporate/government organization setups that are geared with ArcSDE, for better or for worse. Lately, I've been fighting with MS4W to get it to connect to an ArcSDE server that we set up on our intranet (9.3.1 with postgresql, no postgis is the way it was installed). The intranet SDE was set up as a test server, because we can't access the customer's SDE. So why would I want a public facing OSGeo managed SDE instance if I can set my own ? First, looking at the error logs I'm not sure the installation went well. I'd like to debug being sure that the SDE server is functional. Plus, if I want an independent contractor to work on my problem, I can't offer a test instance because it's on our intranet. I realize most of the people that have customers using ArcSDE will test on the customer's ArcSDE service so there might not be a need for a test instance generally speaking. Am I the only one with that (temporary) need of testing a FOSS4G setup on an ArcSDE server ? Would it make sense to have test data (e.g. like in MS4W) set up on a shared test ArcSDE ?
