Re: [OSGeo-Discuss] Best tool, shapefile to png, web
Peter, If all you want to do is render a shapefile to a png image using a command line (once? twice? many times?) then mapserver's shp2img is a good solution, or even GDAL's gdal_rasterize (http://www.gdal.org/gdal_rasterize.html). But if you need a web mapping framework (html, javascript, etc) to provide the end-user with pan/zoom, layer selection and other tools, have a look at GeoMoose (http://www.geomoose.org). If you're using Windows, the MS4W package (http://www.maptools.org/ms4w/) can supply the server-side components, including mapserver. With MS4W, you can install Geomoose and start viewing the demo data within minutes. And if you're looking to maximize performance of web mapping apps by pre-rendering, you're talking about Tiling. One of the best explanation of this I've found is at http://www.maptiler.org/. But it doesn't cover how to create tiles of vector data. I've just started to look into this myself by reading the Mapnik doc (http://mapnik.org/)... Best Regards, Brent Fraser Peter wrote: There is lots of documentation[2] and even a book[3].

Re: [OSGeo-Discuss] Best tool, shapefile to png, web
All, Well, one could go old school, and just store the SHP files as the sourced data. Have mapserver read them directly, either via a dynamically modified index file, or via dynamically built MAPFILE. This would be just about the least amount of moving parts and still get you what you are looking for. I would still suggest moving to a DB a some point, but this would get things organized for a DB move at a later date. bobb Peter web...@pl.net wrote: There is lots of documentation[2] and even a book[3].

[OSGeo-Discuss] Best tool, shapefile to png, web
Hi Guys and Girls, After an embarrassingly protracted google session, im not doing so well. What i need is to turn a shapefile (from a trimble device) into a png as part of a web app. Ideally it would be the simplist lightest tool/s that can do the job, bearing in mind that im working in php/mysql. I found a script which did the whole thing in php (jjfmapper) which functions except development has stopped, and it doesnt support the version of shapefile i have. (jjfmapper reports it to be type 768) The GDAL/OGR library is reported to do conversions of shapefiles to mysql. Would need to add on the png rendering using GD2. Im sure i dont need to reinvent that. And theres something called mapserver which seems to be a complete service. Sounds heavy. The shapefile concerned contains a moderate number of simple polylines. Ideally the end result would be a png, a world file, and/or going further, being able to overlay the png over an aerial photo or png basemap. If your'e interested a sample shapefile is here: http://www.zoneblue.org/files/BLK1_log.shp.zip with the desired result here: http://www.zoneblue.org/files/BLK1_log.shp.jpg Appreciate any pointers.

Re: [OSGeo-Discuss] Best tool, shapefile to png, web
Peter, Ok, this is all going to sound a bit heavy (to use your words), but in the end you'll have a lot more flexibilty with the end toolset. I would suggest loading the SHP file data into a Database, Mysql would work, but POSTGIS would be better. Then source that Spatial data via MapServer and use in any of a number of image clients. I'm partial to GeoMoose, but Openlayers would work too. Looks like you are tracking farm field tractor locations, by entering things into a Database from the start, over the long haul you'll be able to add in things like temporal reporting as more and more data becomes available. This is where the up front heaviness will pay off. bobb Peter web...@pl.net wrote: Hi Guys and Girls, After an embarrassingly protracted google session, im not doing so well.

Re: [OSGeo-Discuss] Best tool, shapefile to png, web
Hi Peter, if you plan to have more shape files in the future you can use MapServer + Gdal. If you use Linux, GDAL and MapServer are pretty easy to install... it integrates very well with Google Maps and it can read any format supported by gdal. hope that helps.. regards On Mon, Aug 16, 2010 at 9:41 PM, Peter web...@pl.net wrote: Hi Guys and Girls, After an embarrassingly protracted google session, im not doing so well.

Thanks for the OpenGeo Suite shout out, but at 250 megs for the download, installing a full database and webserver, I think it's about the furthest thing from light on this list. Hoping to get it to the point where it's a cloud deployment and you could just make what you want to do a handful of api calls, but we're not quite there yet.

BTW, QGIS has mapserver export plugin that exports *.map file and at this time save your layers (e.g. shapefile, etc.) in various format (png, jpeg, agg, etc) and open your mapserver to see web map.

Just to round out this suggestion, mapserver comes with an executble shp2img which does, I believe, exactly what the OP wants.
