### ArcGIS 10 Map Layout Demo in ArcMap

Friday, February 17th, 2012

Stewart Bruce of Washington College gave this tutorial as part of the GT101 course. This demo of how to make an actual layout in ArcGIS ArcMap will show you some tips and ticks to good layouts by running through a complete layout exercise. More information on our GT-101 course can be found at http://geoworkshops.org and more information on the Washington College GIS program can be found at http://gis.washcoll.edu

### Georeferencing in ArcMap by UTMLibrary

Tuesday, January 17th, 2012

This video will demonstrate how to georeference a data file that has no spatial information associated with it (such as a jpeg of a satellite image) to have spatial information. This enables the user to add other geospatial layers to the ArcMap project and have all the layers lined up and projected properly. This tutorial will show you how to do so in ArcMap 9.

Kanal has been posting a number of useful tutorials on ArcMap. Here are a few of them.

First steps in ArcGIS (ArcMap), contrast and comsposite bands (layer stack)

This is a getting-started video for ArcGIS arcmap, add data, layer information, viewing options, arctoolbox, the concept of contrast, changing contrast, calculating statistics and generating a layer stack or composit image for illustration and analysis purpose.

### ArcMap tutorials by GISTutorials: Creating a Seemless Raster Mosaic/ Basic Georeferencing/ Advanced Labeling

Creating a Seamless Raster Mosaic

This tutorial shows how to mosaic rasters and how to correct the seem errors using the raster calculator and the focalmean function. Seem errors occur when two rasters don’t intersect correctly.

This method has changed in ArcGIS 10. It has adopted a python syntax. Also you don’t assign rasters algebraically like in previous versions. Instead you set the output to a new raster (it will be obvious within the Raster Calculator). The new syntax would look like this:

Con(IsNull(“myraster”),FocalStatistics(“myraster”,NbrRectang­le(2,2),”MEAN”),”myraster”)

Basic Georeferencing

This tutorial shows how to take a screenshot from Google Maps and correctly place it in space. This allows you to digitize buildings, roads, etc. from it and have them be correctly spatially referenced.

Advanced Labeling in ArcMap

This tutorial shows how to use the Expression-based labeling features of ArcMap to turn attribute based labels into any text you want.
