A long time ago when there was still printed documentation, the Understanding Map Projections book had a foldout table in the back. The table listed all the map projections and had information about various properties and characteristics. Bojan Šavrič Bojan Savric undertook to update and modernize the table including changing the categories and adding new projections. We hope you like the new style! It will easily fit on a 8.5"x14" or 11"x17" page if you want to print it out. Here's the 11x17 version on my office door: It's complete through ArcGIS Pro 2.5 and ArcGIS 10.8. We're adding 3 new projections to those releases: Adams square II, Tobler cylindrical I, and Tobler cylindrical II. Melita

They look good to me. You might have to go to Tech Support and send the data, if possible, in for the locator team to debug.

If you have the spatial reference, get the ProjectedCoordinateSystem, then the GeographicCoordinateSystem from that. Use the GCS as the target/output coordinate system.

Hi Mark, This page doesn't work for you? Call for Presentations | 2020 DevSummit, Palm Spring, California I did get the Ungerboeck titled page, but waited a few seconds and it reloaded with a place to select a submitter. I was able to move to the next page where I would need to put in a customer number, etc. so I didn't try to go farther. Melita

The original data isn't in Eckert IV, but straight latitude-longitude decimal degrees. Try defining it as the geographic coordinate system 4326 (WGS 1984). Melita

Is it a public WMS? If so, can you post its URL? If not, can you check its Capabilities? Here's an example URL for doing so: http://sampleserver1.arcgisonline.com/ArcGIS/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/WMSServer?version=1.3.0&request=GetCapabilities&service=WMS and a simpler, non-ArcGIS request: for GeoServer: http://localhost:8080/geoserver/wms? service=wms& version=1.1.1& request=GetCapabilities Anyway, one of things it will report is which coordinate systems are supported. I would expect that if you have a map open with the coordinate system set to the NAD83-based one, then add the WMS layer, you may get the WMS layer in NAD83. Melita

Another check. Open up data frame properties and select the Coordinate System tab. What is the data frame's (map's) coordinate system set to? Click Layers, is the testPoints layer listed under UTM? Also, switch to the General tab. What are the Map and Display Units set to? If the layer is properly showing up as UTM, try setting the data frame to the UTM zone, then double-check that the Map units are set to meters. Set the Display units to meters or decimal degrees and see if the data's now displaying properly. Melita

You might want to check out the webinars that the NGS has been giving. Another change is that NGS plans to standardize on meters and (international) foot, so no more official support of the US survey foot. There's currently a comment period going on until 02 December 2019. You can read about it (and comment if you want) here. NGS, working with state agencies, plans to release a new set of State Plane zones. Some states may also opt to update their county / low-distortion projection zones or create a new set. Here at Esri, we are waiting for NGS to release transformation information which will likely include files so we can make sure that we support the format(s) and are ready to include them when the final versions are released. Currently beta versions should be available next year. Melita

Hi Jamal, No, because we're in the process of finalizing 2.5. It is on my list to discuss with the map team for the next release--but only to discuss it! NO guarantees. Melita

Okay, so we don't let you actually tessellate because of data duplication, but the Peirce Quincuncial can be tessellated. It was added in 10.7 / Pro 2.3 or 2.4. Upcoming in 10.8 and Pro 2.5 is Adams in a Square II, which can also be tessellated. Melita

Hi Curtis, How is this any different than working with it in ArcMap? Yes, you can set the data frame to be "unknown" and see the bad data offset because it's not being projected-on-the-fly. Whether it's getting projected on-the-fly or not, the data must be offset or you wouldn't realize that there's something wrong with it. In Pro, the data's still offset. You still need reference data that has the correct coordinate system that you can use to compare against the questionable data. Switch the map between the reference data's coordinate system and the bad data's coordinate system. That will tell you the offset. Bad data is 3x too big or small, there's a unit issue. Data is directly north-south--possibly an ellipsoid/sphere (like Web Mercator versus World Mercator). Melita

Hi everybody, If a layer doesn't have a defined coordinate system, it's not projected on-the-fly. It can't be. The software doesn't know anything about it--the units, the map projection, etc. It will be displayed as-is, just as it is in ArcMap. You can still investigate the unknown data's coordinates by either zooming to it and looking at the status bar or opening its properties and looking at its extent. To match the "clear" option in ArcMap in ArcPro: 1. Add the unknown data to a map 2. Add reference data that you want to compare it to. This can be a base map. 3. Make sure the map's coordinate system is set to the reference data's coordinate system. 4. So the reference data is displayed where it is natively. Nothing is happening to its coordinates or extent. 5. The unknown data is also being displayed natively. Nothing is happening to its coordinates or extent. Now you can compare the location of the unknown data against the reference data. We've reviewed the decision to not let ArcGIS Pro have an "unknown" xy coordinate system a few times. We've always made the same decision. There are too many side issues that arise if we don't have a known coordinate system. Melita

Hi Keith, Yes, you're correct. You may want to look at the geographic_transformations.pdf file--it's located in the ArcGIS Desktop documentation folder. It contains tables of the transformations--extents, "accuracies" (very approximate), and parameter values. Melita
