Identify FDO polygone with same info

[olivier.eckmann]

Hi,

I've an FDO connexion to Polygons.

Orginally, each polygon has an info which is unique, but after some cutting operations, resulting polygon have same info. I would like to identify (locate) polygons with same info.

I could show table, sort on this info and search consecutives lines with sames info. I could export to excel and write macro to find lines with same infos, but is it possible to build a thematic (request) for ex to apply red color to a polygon if another polygon have same info and keep other polygons in white color?

Thanks for any idea.

Hi Olivier,

if my understanding is correct a thematic map would only work if Map was able to group values when creating a theme. But this is not the case.

One approach might be:

- save your data as SQLite (right click on layer in Display Model)

- use SQLite tool to query the sql lite file and use plain SQL to identify the duplicates

- remove the duplicates

- use Map to convert SQLite back to original data format.

Good luck, Rob

Hi Robert,

Thanks for your solution, but if I need to be outside of MAP, it isn't what I want.

I play with DotNet API of AutoCAD and Map ObjectData, it's time to show GIS Platform to develop what I want.
