Introduction to Geographic Information Systems (GIS) ESRM 250/ SEFS 520 Data Management

▫ Create a new geodatabase ▫ Import/export three vector files & raster files ▫ Pack all files & map document into one package

Geodatabase • A specific data organization that holds different spatial information and attribute tables together

Create A File Geodatabase • Data Management Exercises

Import to Geodatabase • Right click on “ANY” geodatabase • Choose “Import” Choose which file to import Feature Class: Three vector files (coverage file need to choose shape; e. g, polygon or arc) Raster Dataset: Raster Files

Three File Types of Vector Data in Arc. GIS Coverage Shapefile Feature Class Coverage is a package layer that composed of polygons, arcs, nodes, label points, and tics. It is the oldest file type in the Arc. GIS. It looks like a “folder” in Windows. Shapefile is used mainly in Arc. View 3. x and Arc. GIS. It is a “file” based structure. One shapefile represents features that are either point, line, or polygon. Feature class is stored in the Geodatabase. It is a “data sheet” structure. Each feature class can not be viewed through windows.

Exporting / Moving Various Files • Changing file type ▫ Right click on target layer Export Choose format Feature Class to… Raster to… Shapefile to… Coverage shape to…

Another way to export coverage To Feature Class To Shapefile

Direct Copy & Paste • Available files ▫ Shapefile to shapefile ▫ Raster layer to raster layers • Workflow

Package all layers and. mxdon-the-go • Another way to pack all files and map document together. • Do not have to repair file paths or do the drive substitution for same task • Stored all symbology setting of all layers • Only one file (executable) and double clicks to open the whole package

Workflow of package maps • Having/preparing a working map document arcmap_basics 2. mxd, saved the map document • Add “Description” in: 1. EVERY Layer properties 2. EVERY Data Frame properties 3. Map Document properties • Save this map document again • Click “Package Map” tool from Arc Toolbox > Data Management > Package >
