I want to use a map (scale 1:10000) of a city (Montreal). I assembled it from several high quality pictures. We need to cite copyrights from GoogleEarth Pro. I have read online resources :permissions page Despite trying this, when zooming in, copyrights displayed before (e.g. Cnes Spot/image...

I am working on a computational model of the abundance of wild pollinators across a landscape. The model itself is complete, and I am now struggling with a post-processing step. I have my GDAL pollinator supply raster that looks something like this (lighter colors mean higher pollinator...

I want to implement genetic algorithm to find optimum location for placement problem with ArcGIS. Can any body explain it (step by step ) or any resources about that? أكثر...

Hi all, I’m creating a new cartography workshop for the Stanford Geospatial Center and was hoping to get some feedback on the general outline as well as ideas for techniques or topics I may be overlooking. First let me describe what the general scope of the workshop is. We have a 3...

Lets say I have two layers, one with county limits and another with roads for that same area. I'm trying to set up an atlas with counties as the coverage layer, so that I get a set of maps, one for each county. How can I set it up so that the roads layer gets clipped by the county boundaries...

I am creating a map with about 50 points and want to label the points numerically (i.e. 1, 2, 3, 4...) and provide a table with the corresponding point numbers in order with additional columns with info related to each point. My problem is I want the point numbering on the map to be grouped or...

I created a TIN from contours and it has errors like: Areas which suppose to be represented as 380 is on 40 meter interval and some which are mountain peaks have lower values. A snapshot is below. Can anyone help me with a method in picking these errors and correcting them? أكثر...

I have two numpy meshgrids (X, Y both 2D) in Lambert Conformal conic with the following information: latitude_of_projection_origin: 25.0longitude_of_central_meridian: 265.0standard_parallel: 25.0earth_radius: 6371229.0I'd like to directly (or indirectly if not possible) project them to UTM. I...

I have thousands of locations that I would like to snap to be placed on top of a hundreds of polylines based upon matching attribute fields. Think of them exit signs located on every interstate-highway in the United States. There will be thousands of locations for the signs and significantly...

I'm working with the WWF ecoregions, which use the GCS_WGS_1984 geographic coordinate system. I have clipped the ecoregions with a species range (consisting of two polygons), but the new attribute table doesn't tell me the new 'clipped' ecoregion areas. From reading around it seems I need a...

I want to delete some fields of featureclasses, but when I run the code FeatureClass.DeleteField(Field) it works well for some featureclasses but after some time it gives an error such as: The field cannot be deleted because it is being used as a relationship key. أكثر...

From time to time I have to access geometry field and shuffle through points in it. Process is simple: Get shape Get it's part Iterate through part's points This is how it looks like in a script import arcpy fc = r'd:\scratch\line.shp' with arcpy.da.SearchCursor(fc,"Shape@") as...

I would like to be able to make selections in sequence between buffers and surrounding areas. This would lead to areas (polygons) being selected repeatedly by 2 or more buffers and I want to be able to make selections and exports, listing every export to belong to a number (or numbers) of...

I have to combine several DEM rasters into one from this source: http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp, so I use Mosaic to New Raster tool. I set up the tool: I input the rasters (all from the same source, same size and no projection); Set up the Pixel Type (32 bit...

I have a point shapefile that is filled with many features. If I have 1 feature selected I need to be able to export certain fields of that selected feature (ID, lat, long) into a dbf file. What tools in model builder can accomplish this? أكثر...

EnerGov, in partnership with Esri, will help Maui County centralize its geospatial data by developing a countywide GIS data repository to support county land management and other processes. أكثر...

I am wondering what the purpose of arcpy.Array() is. It seems an intermediate step between creating a list of objects and performing some sort of conversion, for example, such as in the sample code for the 10.1 help. features.append( arcpy.Polyline(...

I have feature class with 70,000+ records (file geodatabase). I want to make in bulk update on an attribute where the value is NULL.Select by attribute shows that I have 5,000 records like that. Doing it one by one is going to be a pain. In sql pseudo code it should be something like that...
