Hello reef master,
I was processing one date acquired with Lawrance, processed with Reefmaster and post-processed with QGIS.
When opening the attributes tables from the Shapefile generated from the reef master found that the depth value (VALUE COLUMN) shows as Alpha characters (STRING) instead of Decimal numeric type (INTEGER).
I was trying to change stiles base on depth attributes and was not detected as Numeric (INTEGER) Value. As a Workaround I create a new Column and took the VALUES as depth, and formate them as (INTEGER)
Suggestion: to have the Shapefile Colum VALUE as INTEGER for easy integration in any GIS system.
see attached attribute table. and shape files.
regards
Luis
