How To generate Lineament

A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will comprise a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features. Fracture zones, shear zones and igneous intrusions such as dykes can also give rise to lineaments.

RELATIVE PATH IN ARCGIS




When you add a layer to a map, ArcMap stores its path in the map document. When you open a map, ArcMap locates the layer data it needs using these stored paths. If ArcMap cannot find the data for a layer, the layer will still appear in the ArcMap table of contents, but of course it will not appear on the map. Instead, ArcMap places a red exclamation mark (!) next to the layer name to indicate that its path needs repair. You can view information about the data source for a layer and repair it by clicking the Source tab in the Layers Properties window.

HOW TO OPEN MAP DOCUMENT

Launch ArcMap

On the Windows taskbar, click Start, then All Programs > ArcGIS > ArcMap 10. Depending on your operating system and how ArcGIS and ArcMap have been installed, you may have a different navigation menu. If you did not have ArcGIS software download it HERE.

In the resulting ArcMap - Getting Started window, click Existing Maps > Browse for more.


Open an existing map document

In the Open ArcMap Document dialog box, browse to the drive where you installed the file, you can download the tutorial file HERE. Unzip it in your C:// drive. (for further training, create a new folder to save all tutorial datas). You can now click on tutorial.1 map document and click open or you double click


The Tutorial1 map document opens in ArcMap (see image below) showing a map consisting of the US States layer. The US Cities layer is the subset of cities with population greater than 300,000. The left panel of the ArcMap window is the table of contents. It serves as a legend for the map plus has several other uses you will learn about. Note that the Tools toolbar, which is floating on the bottom of the screen on the next figure, may be docked somewhere in the interface. If you wish, you can anchor it by clicking in its top area, dragging it to a side or top of the map display window, and releasing when you see a thin rectangle materialize. If you do not see the Tools toolbar at all, click Customize > Toolbars > Tools to make it visible.
