Following on from previous question Python code that uses arcpy.describe skips if statement?, I have now attempted to include clip analysis and this is my result; I am confused as to what is happening, as I am using .bdyseg.shp which is also in the file geodatabase for comparison and...

I have a year of daily raster datasets (365) that I would like to use the Cell Statistics tool on; however, each raster is located in a separate folder so I cannot add all of them at once. ie: -raster_0001 -raster_0001 dblbnd.adf hdr.adf prj.adf...

I have a series of point that I want to draw circles with varying radii around. The radii depend on the zoom level and represent a 1.1 mile circle from the point. I'm running into an issue where the circles will draw but are clipped. All I've been able to find so far is to increase the buffer...

I have points representing where street light poles meet the ground. I also have the angle which the mast arm is facing. We use this to symbolize the features by showing the mast arm over the appropriate road- sometimes it is not perpendicular to the closest road. I need to associate attributes...

I have an arc layer with points and another with lines. The points exist along the lines (as stations). Both layers have an attribute for LineName. How do I pass the specific line name data to the points layer? In my specific example image, the LineName is displayed but the points table has...

I am trying to create a map from raster data. The file came from a crop model, with resolution of 0.5 degree. Even when I disaggregate it (i.e. increase spatial resolution), the map looks really pixelated. I am trying to make it look better. My current code produces this image: where I would...

I'm calculating Simple Ratio (SR) from NDVI using Raster calculator in Arcgis. Here is expression I wrote in Raster calculator. SR=(1+float[NDVI_apr.tif])/(1-float[NDVI_apr.tif])But when I evaluate this expression, the following error always appear on the screen. GRID ERROR-Unable to open...

Working with the ArcGIS family v10.1 on Windows 7. So, I have this vision for a GIS project that does the following: User opens up ArcGIS Explorer (ideally) or ArcMap (still fine), or I guess even an external website (least ideal) and loads in my project file. It pulls up this map I've made-...

We have points table including vehicle routes.In huge traffic conditions,devices collecting data on route may output redundant points where at any coordinate same points may repeat.We can easily search and remove those points,but we have another issue like this. Since points have threshold like...

I am trying to get the coordinates of the coastline. I have made a shapefile with points selected along the coastline, the coordinate system I have the shapefile under is WGS 1984 UTM Zone 30N. I have used the Add XY Coordinates function to get the coordinates of all the points. However the...

This video shows you how to create a high resolution data layer of a specific feature of interest which would be suitable for use in a GIS project using Google Earth. This follows on from Tip #11 in this series, which showed how to transfer data layers between Google Earth and GIS projects. This...

Using arcpy, is there any way to update the selected records of a feature class' field based on a Selection by Location of another shape file? In other words, update a field in a feature class' point based on which polygon it falls into. Of course, this would draw field information from the...

Hopefully someone can tell me if I am missing something here. I am hoping to built a TIN in ArcScene and run some view shed analysis on it, simple enough but I need to add building heights to the TIN, this was done through an ArcGIS Script. The problem is I can't seem to get the TIN as the input...

I'd like some way to download an extract of OSM data, like GeoFabrik or BBBike, that includes bike lanes. Does anyone have any advice or should I just try and figure them out with Osmosis? أكثر...
