basic questions


Recommended Posts

Hallo everyone,


I have 3 packages (DISTRICT, STATE, LINES) of geo data.  Each package has the following files:






I am interested to edit lines in the layer/package DISTRICT, so that in this layer the lines between states are thicker.


Some basic questions:

1. What open source programm I can use to achive this? (Can I use QuantumGIS?)

2. Which file I should edit?  STATE.shp or LINES.shp?


Thank you for the comments.

first, those are standart file of shapefile, made by ESRI , basically shapefile or SHP contain dbf, prj, shp and shx, so its like a one entity with 4 file inside it.


best way is to edit it via ArcGIS, if you see those file with ArcCatalog (explorer like of ArcGIS) you will see those 4 files as one entity file, but you can achieve it too using other famous spatial program like QGIS for example with some effort


If you only want to thickening some line, you dont need to edit it, unlike in CAD term, in spatial data, those job (thickening line) is a part of visualization data and doesn't affect the real data permanently.
