The four most commonly used ones are points, lines, polygons, and annotation.

Answer 7

Feature classes

Question 8

What is a collection of related feature classes that share a common coordinate system? They are used to facilitate creation of controller datasets (sometimes also referred to as extension datasets), such as a parcel fabric, topology, or utility network. Feature classes that are to be included in an extension dataset are first organized into one.

Answer 8

Feature dataset

Question 9

What is an XML-based file format for displaying information in a geographic context. The information can be drawn in many earth-based browsers, including ArcGIS Earth and ArcGIS Pro. The Version 2.2 has been adopted as an Open Geospatial Consortium (OGC) standard.

Answer 9

KML (formerly known as Keyhole Markup Language)

The complete KML specification can be found at https://www.opengeospatial.org/standards/kml/

Question 10

What is an optical remote-sensing technique that uses laser light to densely sample the surface of the earth, producing highly accurate x,y,z measurements. It’s primarily used in airborne laser mapping applications, is emerging as a cost-effective alternative to traditional surveying techniques such as photogrammetry. It produces mass point cloud datasets that can be managed, visualized, analyzed, and shared using ArcGIS.

Answer 10

Lidar (light detection and ranging) and LAS dataset

Question 11

What allows you to quickly connect to data sources to visualize and analyze large datasets. It provides functionality and flexibility to work with your data and its formatting.
* It references a folder of one or more datasets. Datasets in a MFC are used as input feature data (points, polylines, polygons, and tabular data) to geoprocessing tools. When you create the file, a .mfc file is created. This file points to a directory of datasets that outlines the datasets and their schema in the file, including geometry and time information. You can browse for file datasets in geoprocessing tools and view it’s datasets on the map. The following are examples of when it is appropriate:
o You have multiple shapefiles representing a large area. Each shapefile represents a subset of the area, and you want to use all of the shapefiles together.
o You receive a new .csv file daily with temperature measurements. You want to include the new .csv file as part of a dataset with your existing .csv files.
o You use data that has multiple fields representing the time of an event. You want to use all the fields to represent the time.
o You have parquet files to use.

Answer 11

A multifile feature connection (MFC)

.mfc file extension

Question 12

What is a file format for storing multidimensional scientific data (variables) such as temperature, humidity, pressure, wind speed, and direction. Each of these variables can be displayed through a dimension (such as time) in ArcGIS by making a layer or table view from the file.

Answer 12

NetCDF (network Common Data Form)

Question 13

What format was created as a file format to help simplify the transfer of images and associated image support data (ISD) by reducing the number of independent files associated with a given data product. To meet this requirement, it was designed as a container format that can store a variety of data types together, including images, ancillary data such as shapefiles and tables, and associated ISD. By using a container format, all the data used to support a specific data product can be packed into an type file container. The United States Department of Defense (DoD) and Intelligence Community (IC) have standardized on the format to ensure that data products include everything needed to support of a variety of exploitation workflows.

Answer 13

The National Imagery Transmission Format (NITF)

Question 14

A GIS integrates information about various types of geographic and nongeographic entities, many of which can be related.
o Geographic entities can relate to other geographic entities. For example, a building can be associated with a parcel.
o Geographic entities can relate to nongeographic entities. For example, a parcel of land can be associated with an owner.
o Nongeographic entities can relate to other nongeographic entities. For example, a parcel owner can be assigned a tax code.
* ArcGIS provides many ways to associate features and records with each other in a geodatabase. When setting up relationships between geographic features, the first step is to model the spatial relationships between features. Consider how you can use geodatabase topologies, geometric networks, shared-edge editing, geometry snapping during editing, and geospatial operators in your data model. These methods help you efficiently create and maintain data.

Answer 14

Relationship classes

Question 15

Services can be?

Question 16

What is a Shapefile?

Answer 16

A shapefile is a vector data storage format that stores the location, shape, and attributes of geographic features with the same geometry type (such as point, line, and polygon) and the same spatial reference. You work with shapefiles in ArcGIS Pro in a similar way to working with feature classes. They can be added to the map as a layer and you can work with their fields and properties in the fields view.

Question 17

Tables

Answer 17

A table view is a display of attribute information in a tabular format. In the simplest terms, tables are composed of rows and columns, and all rows have the same columns. Rows are commonly known as records, and columns as fields. Each field can store a specific type of data, such as number, date, or text. Rows and columns intersect to form cells that contain a specific value for one field in a record. The information displayed in a table comes directly from the attribute information stored in the data source.

• The term table can be used to refer to both attribute and stand-alone tables. Attribute tables contain the nonspatial information about a geographic feature. A stand-alone table is a table of attributes that do not have associated geographic features. You can use a join or relate to connect geographic features to a stand-alone table, such as a fire hydrant location with a tabular list of completed inspections.
• In ArcGIS Pro, you work with tables in views. Two types of table views are available, based on how you open the table. You can open the table view of a layer or stand-alone table from within a map or scene to edit values, select or query records, and view related data. You can also open a table directly from the Catalog pane or a catalog view. This opens a table view designed for data management and review without needing an associated map view open. You can control where on your computer screen a table opens by setting preferences in the User Interface options.

Question 18

What dataset is a multiresolution, TIN-based surface built from measurements stored as features in a geodatabase. They’re typically made from lidar, sonar, and photogrammetric sources. Terrains reside in the geodatabase, inside feature datasets with the features used to construct them.

• https://pro.arcgis.com/en/pro-app/latest/help/data/terrain-dataset/terrain-dataset-in-arcgis-pro.htm

Answer 18

Terrain datasets

Question 19

What are a digital means to represent surface morphology. They are a form of vector-based digital geographic data constructed by triangulating a set of vertices (points). The vertices are connected with a series of edges to form a network of triangles. The edges of them form contiguous, nonoverlapping triangular facets and can be used to capture the position of linear features that play an important role in a surface, such as a ridge line or stream course. Because nodes can be placed irregularly over a surface, they can have a higher resolution in areas where a surface is highly variable and a lower resolution in areas that are less variable.

Answer 19

TINs

Question 20

If you have features that are coincident and share the same location of coordinates, boundaries, or nodes, geodatabase topology can help you better manage your geographic data.
o Geodatabase ________ help ensure data integrity. Using it provides a mechanism to perform integrity checks on your data and helps you validate and maintain better feature representations in your geodatabase.
o In addition, you can use them to model spatial relationships between features. These enable support for a variety of analytic operations, such as finding adjacent features, working with coincident boundaries between features, and navigating along connected features.

Answer 20

Topology
