I have a polygon shape file. I used ArcPy scripts to: add a new field to the shape file use Calculate UTM Zones on each polygon. It spits out UTM projection information into the field I've added. I would like to use a cursor to go through each row of the polygon shapefile's attribute...

I have a bunch of latitude,longitude coordinates (mostly city/town centroids) in the United States for which I'd like to find the containing census tract. For instance, input => nn.nnn, -nn.nnn output => 010300Is there a free or low-cost API out there that can help? (Essentially Yahoo...

I am having trouble deleting the features I have selected using 'arcpy.SelectLayerByLocation_management' tool. To use the select layer by location tool, you much pass in a .lyr file. My script SHOULD create a .lyr file of the input data, select by location on the .lyr file, make a copy of the...

I have a very specific question about searchcursor traversing complex polyline. My setup is: I imported public transport routes as a single polyline with length in meters. Along this polyline I want to place points with equal distance between them. For that I have found the following ready...

How to get a bounding box (in the form of a Polygon, or anything else where it's easy to extract the corner coordinates from) of a given Geography item? Something that would look like: SELECT Boundary(geog) AS boundingBox FROM segments; Where geog is a MULTILINE geography. Seems like a...

I'm using the GDAL SWIG python bindings to create a new GeoTiff raster for use in a blockwise exponential-decay function.. kernel_size = 177764054 driver = gdal.GetDriverByName('GTiff') kernel_dataset = driver.Create( kernel_uri.encode('utf-8'), kernel_size, kernel_size, 1...

I have about 20 million sets coordinates from the Philadelphia, PA, USA region. For each set of coordinates I would like the FIPS code of the corresponding census tract. I looked at this thread: Free api to reverse geocode latitude, longitude to census tract? However, I think any http/API...

I am converting point vector data to a raster dataset using nearest neighbor. I am using arcgis 10.2. The first step is to use the conversion toolbox, but there are two possible options: Point to raster Feature to raster What is the right application for each of these? When should I...

I'm struggling to come up with a proj string for a local county coordinate system using pyproj. The system is defined as follows: Linear unit: International foot (ift) Geodetic datum: North American Datum of 1983 (1991) Vertical datum: National Geodetic Vertical Datum of 1929 (NGVD29) System...

Need some guidance here, I have two operational esri js maps that I want to combine to have two different popups. If I/we could somehow figure out a way to add the number of parks to the census popup that would work and not worry about the two popups. But I'd prefer to have info on census groups...

I am attempting to create feature linked annotations for my cable system and I have set up a relationship between the two features so that any changes made to the cables will automatically be updated in the annotation. The cable feature's "GUID" field is set as the origin and I have created a...

Can someone tell me what the projection is in this zone map from NOAA? Addendum: I am trying to replicate it (or get close) in QGIS. I know very little about GIS, but I need to do this for a web development project I am working on. أكثر...

So basically here is my outlined workflow. I have a point layer and a line layer. My points have a cost value associated, and my lines represent highways. All points fall on lines, therefore I would like to iterate my selection so that I can select all points that fall on a given segment, total...
