Please try harder to recognize that geologic surfaces have discontinuities. They are not just a solid, continuous, rectangular grid. There are often linear discontinuities (faults), exclusive holes (fault gaps, salt penetration), and inclusive edges (pinch-outs, erosion, or end of interpretation). And these features need to be displayed as nice smooth features, not stair-steps, zig-zags, scallops, or other unappealing and non-geologic shapes.
Value: many geoscientists refuse to accept or embrace ArcGIS because of these shortcomings. Some of it is purely the aesthetic appeal of the resulting maps, and some is more significant deficiencies in modeling and making calculations on the geologic surfaces.
The Petroleum User Group (PUG) has been pushing this subject for years, as shortcomings in the ability to adequately process and display these features are a significant barrier to increased usage in our industry. Progress has been made, but there is still more needed.
Recognizing progress, we are glad to see:
1. Spline with Barriers: this interpolation tool solves the issue of faults, but the python implementation has some flaws (shift due to rotation) and performs quite poorly in comparison to other interpolation tools.
2. Contour with Barriers: this was a good step forward, but fell short as the Polygon option was never implemented.
Following are the next priorities, which are each documented separately with additional details.
1. Blank Grid/Raster inside Exclusive Polygons: this seems like it should be extremely easy, please just do it. Reference: https://community.esri.com/ideas/7299
2. Color Fill Contour Polygons: finish implementation in Contour with Barriers. Reference: https://community.esri.com/ideas/1387
3. Spline with Barriers: resolve shortcomings in the implementation mentioned above. Reference: https://community.esri.com/ideas/7309
Note: this is a strategic request, consolidating several issues from the Petroleum User Group: http://www.pugonline.org/index.php?q=the-list/ascending
