You can import the data • Exercise 1: Organizing the tutorial you’ve collected from a total station or enter the tape measurements data recorded on a field sketch or a survey plan. Completing the exercises in this chapter will provide you with the basic knowledge to use these capabilities.

Your field crew has performed a survey to relocate some parcel boundary monuments (cid:129) Exercise 4: Creating COGO and to fix the location of buildings for an existing subdivision.

You will use a survey project in your geodatabase to import tions and linked features measurement data for the boundary monuments that were found, and for some corners of buildings on the site of the survey. You will use this (cid:129) Exercise 6: Exporting survey point information to update the geometry of an existing subdivision block in your data geodatabase and add a new building based on tape measurements recorded in the field. You will use a second project to add values recorded on the original subdivision plan. The survey points computed in this second project will be exported for use by the field crew to locate any monuments that were not found in the first field survey. You will use georeferenced images of the original subdivision survey plans as a background for your work. 1 Ch02.pmd 1 5/2/2008, 2:40 PM Introduction to the tutorial Survey project Description To use this tutorial, you need to have the Survey Analyst extension and ArcGIS installed. You also need to have the Carmel Bay Project for managing and entering tutorial data installed on a local or shared network drive on field-based survey data your system. Ask your system administrator for the correct Carmel Sub Plan Project for managing and entering path to the tutorial data if you do not find it at the default plan-based survey data installation path. The default installation path is arcgis\ArcTutor\Survey_Analyst, on the drive where the Feature classes Description tutorial data is installed.

ESRI does not invite reliance on this data for any other purpose, and the user of this data should exercise their own professional judgment when acting on its content. This tutorial lets you explore the basic capabilities of ArcGIS Survey Analyst. The complete tutorial will take you two to three hours to complete. You can also complete the exercises separately if that is more convenient for you.

A survey dataset is a comprehensive collection of survey points, measurements, and computations. You define 3 a single survey dataset to provide survey-awareness for each logical group of feature datasets and feature classes. The survey dataset covers the extents of your management area. Viewing the survey dataset properties 1. In ArcCatalog, click the plus sign next to your new folder connection. Click the plus sign next to the Survey folder. Click the plus sign next to the Arizona geodatabase. 2. Right-click the Arizona survey dataset and click Properties. The packages are the survey data types that can be stored in the survey dataset. In this tutorial, you will be importing and working with field survey data from total positioning station (TPS) equipment, and you will also be 2 using and storing COGO. Once packages are added, you cannot remove them from the survey dataset. The Survey Dataset Properties dialog box appears. 6 ARCGIS SURVEY ANALYST TUTORIAL Ch02.pmd 6 5/2/2008, 2:40 PM 4.

Survey projects are used to organize your survey data into logically 3 structured and manageable groups of measurements, survey points, and computations. You always add new survey data through survey projects. Viewing the survey project properties 1. In ArcCatalog, click the plus sign next to the Arizona survey dataset. Click the plus sign next to the Maricopa County survey folder. 2. Right-click the Carmel Bay survey project and click Properties. 3. Click the Spatial Reference tab.
