![]() ![]() ![]() Name the new field, specifying the field type as eitherįloat or double, according to your needs.ArcGIS allows you to add a new field only if you are not in an editing session. In the attribute table, click Options and select Addįield.To open the layer's attribute table, right-click the data layer, and then select Open Attribute Table.If the coordinate system is undefined, you will need to project the data before continuing. In ArcMap, right-click the data layer and select Layer Properties, and then choose the Source tab. Verify that the data layer has a coordinate system.To create a new field containing values for each feature's area, perimeter, or x and y coordinate of centroid: However, if you do not see this information reported in the attribute table, you can add a new field to an existing polygon feature class or shapefile. Typically, polygon feature classes in ArcGIS already have a length and area field defined. For further details, see ArcMap Retirement in Education Programs. This means that all current ArcGIS Desktop (ArcMap) users will need to transition to ArcGIS Pro or ArcGIS Online by June 30, 2024. Thanks again for taking the time on this.Esri has announced that ArcGIS Desktop (ArcMap and its associated suite of tools, including ArcGlobe, etc.) will no longer be available through the Education Site License beginning July 1, 2024. including the Wilfs_World Multi-poly Shape in question, and the Kids Globe Project has the GDBs etc. I can't upload folders to the forum, so I'm going to share it via Google Drive: Wilfs_World contains my global shapes etc. ![]() I've tried a new project with a fresh GDB and added that shape but it does the same thing, so I don't think its the GDB unless my ArcGIS Pro is building bad GDBs for some reason (again could the Drive E: be the issue?). I'll leave it as is until I hear again from you, but if I don't hear from you by the weekend I'll update then Not the solution I was looking for, but I wonder if that could be part of the issue as well if it's not designed to be run off Drive E:? I have not found any other issues due to it being installed on Drive E:, this would be the first. Oh, that's a lot faster than I was expecting (we ran the generalize tool on what was (I thought at least) a small data set in a MOOC IIRC and it took 3-15 minutes for the students depending on the rig (I'm using a laptop) so I was expecting area calculations on all the weird areas to take longer than 3 seconds (even interpolating for my laptop it should take less than a minute then?).Īs for the version, I'm using Pro 2.5.1: I did try and update that last night but I have it installed on Drive E: and the installer gets broken by that (Error 1327 Invalid Drive D:) Their response on the support ticket this morning was to uninstall my Drive E: version and install on my Drive C. Here's some screens to make sure I'm not missing something obvious. Drew Flater I'm not sure "the layer doesn't have a selection, definition query, etc that limits which records are processed by the geoprocessing tool", but the way I understand it, if I can see in the map pane it's seen by the tool process as well no? And though I did a complete botch job on merging them (the columns were/still are a mess) I don't see how that or anything else on either of those should stop the CGA tool from running.Īlso, I'd like to confirm that this task is run locally, that this isn't some sort of network/credit issue.īeyond that I'm at a loss. This originally is the "ne_10m_admin_0_countries" dataset, so I don't know if there's something there that limits me? Also it was missing Cabo Verde poly so at some point I merged in the Cabo Verde layer found on the CV government site: The same problem occurs when I run the tool on that data. Nothing is happening.įirst of all, I'm very green, and though I'm sure I've done this before in a MOOC, I can't find the lesson now to confirm how I did it, but I feel like there's not too much I can screw up here: as far as I know it should just be calculating and depositing the numbers in the column I made for the purpose, but it's not! It says it's running the process in less than a second, and I know that's not possible (I've added a bunch of islands that even if it had the unedited values cached, it would take more than a second to calculate, and since I'm pretty sure that's not the case, I'm expecting this to take several minutes if not hours!). Rita Hodges Were you able to resolve this? I've been having the same problem this evening (and to confirm, it's not populating the column with "0": I've tried running it on other populated columns and got no change). ![]()
