Hi,   I am having problems when trying projections for mapping in ArcGIS Pro. For a given project, it is always recommended to use the most suitable projection in order to reduce shape/area distortion... It is sensible.   However, in ArcGIS Pro, any time I try a projection on the geographic extent of my project and/or accidently pan & zoom, the… (Show more)

Click to view contentHi   I am working on this map for somebody and I need help to make this line between Far East Russia and Alaska  disappear and which projection is the right one to use for this area ?... I am using ArcGIS Pro 2.4 and use the WGS 1984 Web Mercator  Auxiliary Sphere ?     I made a map and exported it in PDF, TIFF and PNG  in Pro and it came out… (Show more)

Here is a story map about map projections in ArcGIS:   It shows a gallery of 68 map projections supported by projection-engine in ArcGIS 10.7.1 and ArcGIS Pro 2.4.    Happy mapping!

I have some coordinates from Switzerland   X_KOORD Y_KOORD 488200 113800 488400 112100 487600 114100 488500 112100   But they didnt give me a coordinate system. Doing some research I found they use a grid in metters but not sure what is the one they use.     What is the most common grid used in europe?

Simple question: If ArcPro can finally calculate area and distance geodesically, why do we need projections? Why not do all analyses in geographic coordinates and remove the distortion from flattening the curve?? When are projected measurements ever going to be more accurate than geodesically derived areas and distances?
Click to view contentI have data that I would like to line up perfectly. In the past, I have used the align edge tool in the topology tools as a fairly quick and easy way to do this. The dataset I'm working with covers a large area (1:2m scale), so I have all the data projected into WGS 84. In the image I've included, you can see the pink topology edge line doesn't… (Show more)

I have some global data (seismic data from earthquakes) that was provided as geocentric (cartesian) coordinates. Basically, the coordinates range from +1 to -1 for x, y and z axes. The center of the earth is at coordinates 0, 0, 0. I need to convert these to latitude, longitude and elevation (altitude). . I believe I have been able to convert the… (Show more)

Click to view contentI have 40k points the attribute table has multiple x and y fields all have different numerics.  None of them seem to match any coordinate system.   Can someone explain the format of these columns   Projected Coordinate System:    NAD_1983_StatePlane_Arizona_Central_FIPS_0202_Feet_Intl Projection:          Transverse_Mercator False_Easting:  … (Show more)
