How to open polygons with extensions of .cor & .dsp

SamLimerick — Sun, 27 Dec 2015 16:13:35 GMT

I have some polygon files with extensions of shp, dbf, prj, cor & dsp. ArcCatalog reports "error opening feature class". Any ideas how to convert these to readable shapefiles? .cor may be CorelDraw, probably not Trimble; dsp has me baffled. Thanks!

Regarding .shp, .dbf, and .prj, those are components of a shapefile. Typically, you'll have about 7 file components of a shapefile - not all are required, but you absolutely must have at least the following:

.shp

.shx

.dbf

Here's the complete list:

.prj — projection format; the coordinate system and projection information, a plain text file describing the projection using well-known text format
.sbn and .sbx — a spatial index of the features
.fbn and .fbx — a spatial index of the features that are read-only
.ain and .aih — an attribute index of the active fields in a table
.ixs — a geocoding index for read-write datasets
.mxs — a geocoding index for read-write datasets (ODB format)
.atx — an attribute index for the .dbf file in the form of shapefile.columnname.atx (ArcGIS 8 and later)
.shp.xml — geospatial metadata in XML format, such as ISO 19115 or other XML schema
.cpg — used to specify the code page (only for .dbf) for identifying the character encoding to be used
.qix — an alternative quadtree spatial index used by MapServer and GDAL/OGR software

Shapefile - Wikipedia, the free encyclopedia

Make sure the shapefile you are attempting to open has the three mandatory files - I would recommend you have the .prj as well, so long as it's valid (looks like you do). If you don't have it, but are 100% certain of the projection, you can define this in ArcMap using the Define Tool. Like I said, only use this if you need to define the .prj and know the projection used to create the shapefile originally.

Here's some info on salvaging a corrupt shapefile, if that's an issue for you:

Regarding the other files, it's been awhile, but if I'm not mistaken, a .cor is a post-processed/corrected .ssf - you should be able to export from Pathfinder to shapefile. Regarding the .dsp - this may be related to Optitex (a CAD software); a marker file:

Optitex | 3D Virtual Prototyping, 2D CAD Pattern + Fashion Design Software

Knowledge:CAD File Extension - OptitexHelpEn

Marker:Save As - OptitexHelpEn

I have no experience with this software...

Use ArcMap and see if the Add Data option will open the shapefile.
