I'm looking for a way for a user to draw a polygon and return how many "tiles" cover the polygon. if you have code or can help make this happen, I can make it worth your while.
tiles are in a regular grid covering the state of VA. I have .shp and .kml files representing grid. Three grid scales are: 10k x 10k blocks, 5k x 5k blocks and 2500ft x 2500ft blocks (takes over 750K blocks to cover state). origins of tile grids are the same. also having trouble displaying large kml files...so grids may be displayed on screen only when appropriate/possible (when zoomed into a certain scale) or tiles are selected. also need way to "snapshot" map for inclusion in pdf links: current application here: http://www.VBMPselect.com/map.php grid description here: http://www.vbmpselect.com/vgin_grid.pdf (page 12) grid kml here: http://www.vbmpselect.com/grids_kml.zip grid .shps here: http://www.vbmpselect.com/state_shp.zip test .shp files that a user might upload: http://www.vbmpselect.com/test_shps.zip basically trying to "identify coverage" such as at: http://maps.firstbasesolutions.com/map.php overview of project here: The goal of the application is to allow a user to select “tiles” of geospatial data in order to generate a product/price order document. To compute pricing, I need the ability to draw a polygon or upload a .shp on a google map in order to determine # of tiles that cover a given area at various scales (then those tiles are priced according to a price list, and summed in the pdf) I have everything working except for way to draw poly/get count and upload/export .shp files. specific functions required are: 1. ability for user to to draw polygon on gmap to determine (and highlight) # of tiles intersecting the polygon. polygon count process must take into account adding tiles that cover a certain area at a given scale 2. Ability to rapidly draw tile grid on map (currently have this as a .shp or kml file...see links above) a. Implement radio buttons in custom menu over lay to turn these reference layers on/off b. Tile grids come in 3 map scales depending on resolution of data. 2500ft x 2500 ft grid (3 inch data), 5k x 5k grid (6 inch data), 10k x 10k grid (1ft data) 3. Ability to export polygon as drawn as a .shp file in appropriate projection -thanks! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
