Lining Up Data in ArcGIS: A Guide to Map Projections is an easy-to-navigate, troubleshooting reference for any GIS user with the common problem of data misalignment. Completely updated with full-color maps and diagrams from ArcGIS Desktop 10.6 but still compatible with ArcGIS Desktop 10.1 and higher, this book presents practical techniques for identifying data projections and creating custom projections to align data. Formatted for practical use, each chapter can stand alone to address specific issues related to working with coordinate systems. With an added chapter on vertical coordinate systems, plus a newly available data download, the third edition of Lining Up Data will benefit new and experienced users alike.
Margaret M. Maher is an 18-year member of the Esri Support Services team. She has helped resolve more than 16,000 cases involving problems with map projections and data conversions. She has written numerous articles about ArcGIS Desktop for the Esri Support Knowledge Base.
Preface
Introduction
Chapter 1 Identifying the type of coordinate system for data using ArcMap
Using vector datasets
Identifying the type of coordinate system for data using ArcMap
Summary
Chapter 2 Identifying the correct geographic coordinate system
Example of datum offset between NAD 1927 and NAD 1983 datums in a GCS
Example in which data with the unknown coordinate system is in a GCS, and reference data is in a projected coordinate system
Other issues to consider
Summary
Chapter 3 Identifying the projected coordinate system
State plane coordinate system
Universal transverse Mercator (UTM) coordinate system
Testing to identify the projected coordinate system for data
If state plane options do not align the data, test for UTM
Other projected coordinate system options
Summary
Chapter 4 Applying nonstandard units when standard coordinate systems don’t work
Customizing the state plane coordinate system with units of inches
Comparing units of international feet with US survey feet
Saving the custom projection file to disk for future use
Defining the projection using the custom projection file
Summary
Chapter 5 Aligning CAD datamodifying a standard coordinate system
Working with CAD files in ArcMap
Procedures to address misaligned CAD data
1. Identifying units of measure
2. CAD files created with references attached
3. If CAD data is in nonrotated local coordinates
4. Rotated CAD files
5. Improving layer/level visibility
6. If CAD files were created in ground coordinates
7. The scale factor may be applied to the false easting and false northing
8. If the data lies below sea level
9. Applying the custom coordinate system to the CAD file
Saving the custom projection file to disk
Summary
Chapter 6 Aligning rotated CAD data
Adjusting for the azimuth or rotation parameters
Using other custom coordinate system options
Summary
Chapter 7 Why do we need geographic (datum) transformations?
What are geographic transformations?
Geographic transformation methods
Creating custom geographic transformations in ArcToolbox
Summary
Chapter 8 Applying horizontal geographic transformations
Applying geographic transformations in ArcGIS 10.x for Desktop [note: The process from 10.1 on is the same, but if we say 10.5 or 10.5.1 people will think the process described only works at that version.]
Applying geographic transformations to the ArcMap data frame
Applying geographic transformations in the Project tool in ArcToolbox
Summary
Chapter 9 The importance of vertical datums; how to apply them; and how to transform them
Types of vertical datums, their relationship, and their uses
Steps to apply a vertical datum to 3D data in ArcGIS Desktop
When is a vertical datum transformation required, and how to perform it
Summary
Chapter 10 What map projection should I use for my project?
Geographic coordinate systems
Projected coordinate systems
Deciding on the projection to use for your project
Creating the custom projection file in ArcMap
Appropriate use of the web Mercator projection
Summary
Chapter 11 Defining projections and their parameters; adding x,y data; analyzing the shape of buffers
Coordinate system definitions provided with ArcGIS for Desktop
Coordinate system parameters
What is a geographic coordinate system?
What is a projected coordinate system?
What is a local coordinate system?
Adding x,y data to ArcMap and converting to features in a shapefile or geodatabase feature class
Why buffers displayed in ArcMap are not round
Summary
