Chapter 10 GIS Project Management Figure 10.8 Grid versus Ground Measurements In addition to EF and SF errors, care must be taken when surveying areas greater than 5 miles in length. At these distances, slight errors will begin to compound and may create noticeable discrepancies. In particular, projects whose length crosses over coordinate systems zones (e.g., Universal Transverse Mercator [UTM] zones or State Plane zones) are likely to suffer from unacceptable grid-to-ground errors. While the tools and techniques outlined in this section may be considered beyond the scope of an introductory text on GISs, these pages represent some of the concerns that will arise during your tenure as a GIS project manager. Although you will not need a comprehensive understanding of these issues for your first GIS- related jobs, it is important that you understand that becoming a competent GIS user will require a wide-ranging skill set, both technically and interpersonally. KEY TAKEAWAYS • As project manager, you will need to utilize a wide variety of tools and techniques to complete your GIS project. • The tools and techniques you employ will not necessarily be included as a part of your native GIS software package. In these cases, you will need to apply all project management resources at your disposal. 10.2 GIS Project Management Tools and Techniques 247

Chapter 10 GIS Project Management EXERCISE 1. Consider the following GIS project: You are contacted by the City of Miami to determine the effect of inundation due to sea-level rise on municipal properties over the next hundred years. Assuming that the sea level will rise one meter during that time span, describe in detail the process you would take to respond to this inquiry. Assuming you have two months to complete this task, develop a timeline that shows the steps you would take to respond to the city’s request. In your discussion, include information pertaining to the data layers (both raster and vector), data sources, and data attributes needed to address the problem. Outline some of the geoprocessing steps that would be required to convert your baseline GIS data into project-specific layers that would address this particular problem. Upon completion of the geospatial analysis, how might you employ cartographic principals to most effectively present the data to city officials? Talk about potential problems that may arise during the analysis and discuss how you might go about addressing these issues. 10.2 GIS Project Management Tools and Techniques 248
