Zonal Statistics as Table: Overlapping Polygons: Solution Required I'm currently using ArcGIS 10 SP2 on Windows 7 64bit. I'm working on a very large railway alignment design project and need to generate "Average Catchment Slopes" for each watershed. The problem that I have is that th... Find percentage of raster classes inside polygon I have a raster representing glacierized area with 2 classes: distinction between ice and snow. I also have DEM of the area. I would like to calculate an average height of the boundary between those two classes. I cam... Too many contours to TopoToRaster into elevation? Simply put, I am trying to convert 10m contours of an island into a rough picture of the elevation - there is no need for high accuracy here Upon running the topo to raster tool it says there are too many points (15... Error in calculating Area Solar Radiation I am trying to calculate Area Solar Radiation (Spatial Analyst -* Solar Radiation - Area Solar Radiation) from the Canada3D DEM map. I always get the following error: ERROR 010016: Error in calculating horizon ... Intersect stream layer with another layer and preserve its flow direction? Hi everyone, I'm wondering if there is a way to intersect a stream segment layer (created by ArcHydro) with another layer (e.g. a grid) but preserve its flow direction (sample in fig. below). The reason for doing thi... Convert integer raster grid to float grid using one specific column in VAT I have a integer raster grid which has a value attribute table with these column: Rowid, VALUE, COUNT, AWC_100, AWC_150 ... I want to convert that grid to a float one using the column AWC_150 from the VAT in ArcGIS 10... Time series interpolation in ArcGIS Dear all, I'm trying to calculate average rainfall value from a number of points using Inverse Distance Weighted tool in ArcGIS 9.3.
