![]() Here is the part of my code containing the calling to the tool (Everything else is working - already tested): arcpy.AddField_management(net_clip, 'LAT', 'DOUBLE')Īrcpy.AddField_management(net_clip, 'LON', 'DOUBLE')Īrcpy.CalculateGeometryAttributes_management(net_clip,Īnd here is the error message I get: Traceback (most recent call last):įile "D:/ArcPy_Classes/Scripts/sampling_sig.py", line 90, in Īrcpy. Is there any other way to calculate the centroids? By doing this, the PointX and PointY attribute fields will calculate Decimal-Degrees. If your data is in another coordinate system, go the Environment Settings of the GP tool and set the Coordinate System to be WGS 1984. I've searched around and found that maybe the only version of ArcGIS that supports this tool on ArcPy is ArcGIS 10.6, and which I have here is ArcGIS 10.5. In ArcGIS Pro, you could use the Add XY Coordinates GP tool to create 2 new attribute fields. If you click on the points generated by the feature to point tool I can extract the coordinates from the bottom of the pop-up, but that's no ideal at all.I've been trying to run some code in Python with ArcPy library.Įverything is working fine, but in the end of the code there is a part that I want to calculate the centroids, x and y, with CalculateGeometryAttributes_management(), like when we calculate field through ArcMap directly from attribute table, but it returns some error saying that the "module" object has no attribute "CalculateGeometryAttributes_management". I've used three different county layers so far, ran them through the feature class to feature class tool after the first attempts didn't work, used the Add Geometry Attributes tool, used the Feature to Point tool, and combined the tools in every way I could think of. I just have two fields fill of values even though the tool runs successfully. Geometry Operations with ArcMap Field Calculator Field Calculator is one of the most frequently used tools within ArcMap: taught as part of nearly every introductory GIS course, it offers spreadsheet-like features to the normally static attribute table. Please note that you can also calculate the X and Y coordinates of a polygon or line centroid using this. Knowing the conversion factor for feet to meters and the metersPerUnit property should get you most of the way, or adding a field and using the field calculators shape.lengthfeet like you mention before. Calculate Geometry function in an attribute table. Im using arcpy.CalculateFieldmanagement for this since there already is a selection. Select a few parameters and click OK and then the longitude and latitude fields should populate with the coordinates, right? For now youll need to use a workaround, the length will always be in the linear unit of the spatial reference of the geometry. 1) How to switch the data frames coordinate system and calculate based on it. Create two new fields of type double, label them appropriately, right click, and select "calculate geometry". The feature to point tool quickly creates a point layer with the centroids, but the coordinates are not added to the attribute table. I'm trying to get coordinates for the centroids of the counties in a state. CENTROID Attributes will be added to store the centroid. ![]() AREAGEODESIC An attribute will be added to store the shape-preserving geodesic area of each polygon feature. AREA An attribute will be added to store the area of each polygon feature. ![]() For the X coordinate of the point itself you calculate the X of the point's Centroid. ![]() There is no extent for a point, only for a buffer polygon around a point. maybe How to Calculate the Perimeter of a Hexagon Tessellation: The Geometry of Tiles. 1 Solution by RichardFairhurst 09-13-2013 12:04 PM Thanks, But I bet your fc is a line feature class. But right now, I'm having a hell of a time getting it to work. Calculate Field (Data Management) ArcGIS Pro 3.1 Other versions Help archive Summary Calculates the values of a field for a feature class, feature layer, or raster. Specifies the geometry or shape properties that will be calculated into new attribute fields. Create Hexagon Tessellation - ArcGIS WebTo create a hexagon plot. the docs (see link above) specify that for Python code, you should enclose field names. arcpy.CalculateFieldManagement ('sample.shp', 'LAT', '.X, Y', etc. Looking for some examples on how to do this. It's one of the most basic things that we can do in GIS. How do I Calculate x,y from existing shape geometry using Arcpy. Does anyone know if it is possible to Calculate Geometry with Arcpy I need to replicate the command > Right click field and Calculate Geometry except with Arcpy as I need to integrate this into my model. ![]()
