<div>Hi Everyone,</div>I am an experienced user of ArcGIS, starting over with QGIS. I frequently use MS Excel to create a table of attributes, then load into GIS and join these attributes onto an existing shapefile.<div>1. I tried doing this with Join Attributes and selecting the CSV file. However I found that when QGIS reads in the CSV file, it casts all of the columns as Text, so I couldn't use the numerical values. I notice the Join Attributes from CSV feature is new in QGIS 1.5.0. Maybe there is a bug?</div>
<div>2. Eventually I will want to put my data into a database. I notice I can choose between SpatiaLite and PostGIS. Which is easier to use? Is there a performance difference?</div><div>3. In ArcMap, I frequently used the capability to vary the thickness of line features according to a value in the attribute table. I notice that this capability is available in QGIS only for points ("drawing by field") but not for line features. Is there another way to accomplish variable thickness lines in QGIS? If not, is "drawing by field" for line features under development?</div>
<div><br></div><div>I would appreciate any help you can offer as I am getting started with QGIS.</div><div>Regards,</div><div>Mike</div><div><br><div><br>
