Esri ArcGIS Desktop Associates Part 1
Questions and Answers 100% Pass
What is LAS data - ✔✔The LAS dataset is a file in a folder for lidar data and may show
surface charateristics.
What is the difference between a mosaic dataset and a raster catalog? - ✔✔A raster
dataset requires you to write the entire raster dataset to disk, whereas a mosaic dataset
only references the source files (such as the LAS dataset), thereby taking up much less
space and being much faster to create. You can also modify the surface type in a mosaic
dataset (such as bare earth or first return); however, a raster dataset can only be stored
using one surface type that cannot be altered. Also, you can query the data held in a
mosaic dataset by information such as location and date.
What is the feature class to feature class tool used for? - ✔✔To create a copy of a feature
class without certain attribute fields.
When should you use the repair geometry data management tool? - ✔✔To inspect
multiple features in a feature class and automatically fix their geometry. Example:
remove duplicate vertex, overlapping polygons will be dissolved, null geometry values
will be deleted.

, How to repair broken data links in content panel? - ✔✔Filter contents by broken data
link and select properties. Change the datasource for that layer.
What is the append tool used for? - ✔✔Use this tool to add new features or other data
from multiple datasets into an existing dataset.
When to use define coordinate system? - ✔✔When dataset has an unknown or incorrect
coordinate system defined.
What is a projection, transformation and coordinate system? - ✔✔Projection - A
projection is the means by which you display the coordinate system and your data on a
flat surface, such as a piece of paper or a digital screen.
Coordinate System - a frame of reference for your data, to locate features on the surface
of the earth.
Transformation - convert data between different coordinate systems.
Good process for exporting raster data. - ✔✔Use the Export Raster Data dialog box.
What is the difference between short integer and long integer? - ✔✔Short integer is -
32,768 to 32,767 only. Long integer can be used for larger integers.
What is raster pyramids used for? - ✔✔Displaying large rasters more efficiently.
What type of geodatabases are there and what are they used for? - ✔✔Personal
Geodatabase - 2 GB max, single user. (File)
