/r/gis is a community dedicated to everything GIS (Geographic Information Systems). Please take a minute to read the FAQ below and search through our post history. If you don't find what you need jump in and submit new content. A geographic information system or geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. - Wikipedia ArcGIS Community - maps, applications, blogs, forums, documentation, etc for specific mapping communities Lynda (training service, potentially free through your public/school library) ArcGIS Essential Training We are trying to include as much as we can here at /r/gis but there is information spread out in other subs. Here are just a few: I have a large shapefile of the river systems in Georgia which looks something like this: http://imgur.com/689Wc6w. I want to take one portion of this shapefile (which I want to select by hand), and save it as one brand new shapefile (not multiple). How can I do this in QGIS? I also have access to ArcGIS but I am not as good with it. Any help would be greatly appreciated! use the select tool or select features using expression then edit >, copy features >, paste features as >, new vector layer Or select the features you want to keep and then right click the layer and choose 'save as' and tick the box 'only export selected features.' Not necessary, you can paste as new layer beginning w qgis 2.2. This is nice because if you have WKT from another program in your clipboard, you can paste it right into QGIS. Here's another method which doesn't replicate data (no new shapefile creation but does accomplish what you need). This will limit the shapefile to just the rivers that satisfy the query. In this example, only rivers that found within the four digit HUC 0316 (which is in Alabama, not Georgia). Select your rivers by hand. Open the Field Calculator and create a new field, call it 'Visibility' for example. Just put a number in the calculator field and execute. It will only apply the value to the selected features. I prefer this method of restricting data from larger datasets instead of constantly replicating data. A more elegant process in my opinion. Plus, if you need to expand the scope of your work, you just alter an expression, not create yet more shapefiles. With Arc you can use the editor tool to create a polygon that covers the area that you want to save, then use the clip tool with the river system as the input and the newly created polygon as the clip feature. There's a freehand selection tool in QGIS, you can use this to draw a selection around the river you want to highlight. You then select copy. Then create a new blank Shapefile, make sure it is a line, save it and then toggle editing. Paste the river you selected into the new Shapefile. Source.
