Mapping & GIS
I want to visualize/mashup many of your Web Map Services in ArcGIS Online, or even ArcMap. But, I'm not having much luck with ArcGIS. Is there some guidance you can provide to help me here. I'm sure I'm not alone with this request and as ArcGIS Online is becoming more proliferate other will want to leverage your great services themselves in their own mashups.
We have downloaded the population estimate data for France (frap05ag.asc). When we use this file to calculate population for a given polygon, it does not match the response returned by the Population Estimation Service provided. We were wondering what is your criteria for including a grid cell in the calculation? Are you giving weight to a cell based on polygon intersection area? Also, wanted to clarify the xll, yll corner values - do the values -6, 40 represent the center of the bottom left cell or do they represent bottom left corner of the bottom left cell?
How do I open ArcInfo Interchange file (.e00) in ArcGIS?
