RE: RE : RE: RE : RE: [OSGeo-Discuss] GPRS connection API
Hello again, if you can send commands to the GPS receiver through the serial port, then you can program an access from your application in the same way. You can use javax.comm.* or gnu.io to get access to serial ports. Once you have that, it's up to you to communicate with the receiver. I don't see the needing to access through GPRS. FYI, you can have a look at the wource code of gvSIG Mobile [1]. It uses GpsTools (which depends on gnu.io for serial access) for managing communication with the GPS (NMEA parsing, ...). You can look for it at the libGPS library. If I'm missing sg. don't hesitate to keep on asking.

Ari, Traditionally, there has been no widely adopted vendor/system-independent format for specifying style information. Hopefully now that there is an organization (the OGC) addressing open standards for geographic data (including styling: SLD) there will be more support for a styling standard. Wouldn't it be great if data suppliers delivered a .sld (or something like it) with .shp? And Open Source software like Quantum, gvSig, OpenJump, and Mapserver actual read the styling and applied it?

RE: [OSGeo-Discuss] Proposal: OSGeo Cartographic Library
Thanks for the pointer, that's a nice dataset. Opening these 39 layers makes me ask why there's no style information? Pardon my ignorance on digital cartography, but is it because of standards or something else? How do Arc* tools do it? Think of three separate boxes. One is tabulart data (tables), in the ESRI world these are youf *.dbf files, another is geomatery (lines, points, polygons) found in your *.shp files and the final box is the styling (realy schnzy shirts and ties) equivalent to SLD in the open source web mapping world but ESRI also has their cartographic representations layer (or something like that). Often in digital geomatics we focus on the data and geometry. Usualy they apear seamlessly the SHP is connected to the DBF. So now we are talking about adding in the third box in a standards compliant, interoperable and open source manner (I am assuming)... Why do you arc tools have styling?. Perhaps someone has created the styling as is often the Value add portion to data resellers like DMTI. But the styling is based on the data... So it has nothing to do with the data and relatively nothing to do with the software as GRASS, QGIS, JUMP, UDIG, MAPSERVER can all save projects with various styling, they just don't all use the same approach. Some approaches like SLD's (Styled layer descriptor) or context documents (maybe not full styling) help with this. I think these issues are a PART of this proposed library but I don't think is the focus as styling is covered with SLD and context documents etc. Cheers ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

RE: [OSGeo-Discuss] Proposal: OSGeo Cartographic Library
Hey folks, Lots of good discussion going on around this proposed library. From the sounds of it there are many different camps of thinking on this subject which is great. Of course there are many approaches that can be used. Perhaps we might want to talk a little more about the high end user needs and work backwards. For instance if the end user does not want PDF's or has other requirements then symatical debate on the best PDF engine may not be required right now. There is an end User Needs section http://wiki.osgeo.org/wiki/OSGeo_Cartographic_Library#End_User_Needs where PDF is only one required output. For starters I think bringing the FOSS4G world into the world of cartographic product production would be a huge jump. Whether is be digital-digital or digital-paper. Being able to do this using many applications and some custom API I think would keep flexibility open. So if many libraries can be included, lets include them. We'll all have different user requirements. Of course staying standards based where possible would be ideal so using context documents or SLD or something simmilar as an optional output would increase up take. As a final user product I would love to see something that ties easy drag/drop, point and click interactive design interface with real time screen refresh that could produce something akin to a Generic Maptool Tools (http://gmt.soest.hawaii.edu/) script to produce a preview before I print it. Of course having options to use java and python to script workflows would suite the needs of power users who balk at GUI's. I know that the seprate projects will be responsible for the GUI. If we work backwards from the functionality of the GUI though I think we can find the pieces we need. Infact producing a full cartographic map layout in SCRIBUS or using it's technology might be the best way to not reinvent the wheel for the end user. Has anyone thught out the Pseudo code for the process? Posted on wiki http://wiki.osgeo.org/wiki/OSGeo_Cartographic_Library#Worflow * read geo data * geometries * projection * metadata (if required) * apply styling * feature to style coding * Cartographic edits * overide some of the geometry if required (eg roads don't run through lakes) * manual edits / retouching * Produce other cartographic edits objects * create suround * create grids * create legend * create scale bar * create north arrow * Copyright notices from text file or DB * Licensing notices from text fiel or DB * Other * Output size La la la I'll post this to the wiki, maybe flushing this step out will allow us to match a library(ies) to a task(s). Hopefully we don't get hung up too much on choosing a narrow selection of libraries and keep the carto library itself quite open and flexible. Just some thoughts. ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

RE: [OSGeo-Discuss] Newbie Question? Any feature for classification?
Saka, If you're wanting to use some open source languages in the .NET framework there are pythonNet http://pythonnet.sourceforge.net/ which might open up the Python Cartographic Library http://zmapserver.sourceforge.net/PCL/ I looked for something in the JAVA world, but no luck (does not mean there is nothing). If there was then the Java Topology Suite (http://www.vividsolutions.com/jts/jtshome.htm http://www.vividsolutions.com/jts/jtshome.htm ) might have been an option You can also take a look into doing something using GDAL/OGR http://www.gdal.org/ for your task bellow. Not sure if it would fit, but I have seen gdal/ogr do some pretty nifty things. Various bindings available.

Brent Fraser kirjoitti: Ari, Traditionally, there has been no widely adopted vendor/system-independent format for specifying style information. Hopefully now that there is an organization (the OGC) addressing open standards for geographic data (including styling: SLD) there will be more support for a styling standard. I looked around in the web a bit and found this: http://utpjournals.metapress.com/content/b584484743vk910g/ (I don't have access to Cartographica so can't read this). ESRI seems to have .mxd files, which is their map definition file. It's a binary format and probably not documented. Then they have ArcXML (AXL) which serves the same purpose () as Mapserver mapfiles. BTW, mapfile format is a result of a lot of thought and practical experience. I believe some tools (QGIS?) can export mapfiles (can they import them?). OGC Styled Layer Descriptor specification does not impress me, and it's WMS implementation specific. GDAL has feature style specification: http://www.gdal.org/ogr/ogr_feature_style.html It has recently gained some new interest. In my work I deal a lot with scientific data and geovisualization type of thing, and it would be very useful to be able to import and export visualization information files from desktop apps. Sometimes the problem solving could be based on shared development of such files.

RE: [OSGeo-Discuss] GPRS connection API
Check out sourceforge.net and do and advanced search using GPRS and JAVA.

Perhaps you could integrate your fleet tracking with cell phone use http://www.opencellphone.org/index.php?title=Main_Page As usual the Linux Community has turned GPRS into a HOWTO http://www.xs4all.nl/~ernstagn/GPRS-HOWTO/ Hope some of those point you in the right direction...

I believe some tools (QGIS?) can export mapfiles (can they import them?). While I think it is ok to store styling information in a map definition file, I think it should be used only if the user has applied their own styling, different from the default supplied with the data. Just like .prj files tag along to define the geometry of a geographic dataset, a default style file (.OSF?!) should tag along to define the default rendering. OGC Styled Layer Descriptor specification does not impress me, and it's WMS implementation specific. GDAL has feature style specification: http://www.gdal.org/ogr/ogr_feature_style.html It has recently gained some new interest. I missed that! Thanks for the link! In my work I deal a lot with scientific data and geovisualization type of thing, and it would be very useful to be able to import and export visualization information files from desktop apps. Sometimes the problem solving could be based on shared development of such files. Good point. For me the lack of default styling info is a major productivity killer. Our users want to importl basemap data, then spend their time solving geographic problems, not setting ROADS=RED, RIVERS=BLUE, etc. If you are using styling to expose subtler patterns in data, it's even more important to be able to share it.

Re: [OSGeo-Discuss] Proposal: OSGeo Cartographic Library
Actually the origional point was valid; SLD is pretty darn WMS specific. That is why we got them to split it into two; SLD for the WMS concepts of layers and so on; and SE for the really good part (FeatureTypeStyle and friends). For more fun and games drop by the osgeo standards email list and we can leave these nice people alone.
