Question 1

Layers such as digitized contours, water bodies, and railroads from USGS topographic maps are used in GIS as:

Accepted Answer

Digital Line Graphs (DLGs) are digital representations of cartographic information in vector form, including features such as contours, water bodies, and railroads, which are commonly extracted from USGS topographic maps for use in GIS.

Question 2

Which of the following is a source for obtaining TIGER/Line files?

Accepted Answer

TIGER/Line files, which contain detailed geographic data such as roads, boundaries, and hydrography, are provided by the U.S. Census Bureau.

Question 3

VGI represents which of the following?

Accepted Answer

VGI stands for Volunteered Geographic Information, which refers to geospatial content generated by users, often through platforms that allow individuals to contribute geographic data.

Question 4

SDTS represents:

Accepted Answer

SDTS stands for Spatial Data Transfer Standard, which is a "neutral" file format designed to facilitate the transfer and sharing of spatial (geographic) data among different systems. It is not directly readable by all GIS without conversion (A), nor is it a "universal" file format readable by any GIS without potentially needing conversion (C), nor is it a compressed version of a shapefile (D).

Question 5

One or more data layers can be contained inside a:

Accepted Answer

Layer packages can contain one or more data layers, allowing for the sharing and distribution of geographic information in a single, compressed file.

Question 6

Which of the following is an example of VGI?

Accepted Answer

OpenStreetMap is an example of Volunteered Geographic Information (VGI), where users contribute geographic data voluntarily, unlike the other options which are primarily generated or curated by companies or government entities.

Question 7

Descriptive information about GIS data refers to:

Accepted Answer

Metadata is the correct answer because it describes the content, quality, condition, and other characteristics of GIS data.

Question 8

Metadata refers to:

Accepted Answer

Metadata is descriptive information about data, detailing aspects such as content, format, source, and structure, which helps in understanding, using, and managing the actual data.

Question 9

International metadata standards that have been adopted in North America are:

Accepted Answer

The answer of International metadata standards that have been adopted...

Question 10

Which of the following is not a type of data available through ArcGIS Online?

Accepted Answer

Model data is not typically available through ArcGIS Online. ArcGIS Online primarily hosts basemaps, map packages, and layer packages for GIS projects, rather than model data which is more about analytical or simulation models not directly provided through this platform.

Question 11

Requesting one county's worth of transportation data from The National Map will result in what extent of data being obtained?

Accepted Answer

The answer of Requesting one county's worth of transportation data...

Question 12

How are geodatabases currently obtained via The National Map?

Accepted Answer

Data are directly downloaded from the National Map, allowing users to access and retrieve geospatial data without the need for physical media or waiting for email links.

Question 13

The National Map is operated by:

Accepted Answer

The National Map is operated by the United States Geological Survey (USGS), which is a scientific agency of the U.S. government. The USGS is responsible for providing reliable scientific information about the natural resources and natural hazards of the country, and The National Map is one of its key tools for disseminating geographic information.

Question 14

Which of the following types of data is not available through the National Map?

Accepted Answer

The National Map provides a variety of data types including US Topos, National Land Cover Database, and the National Hydrography Dataset (NHD), but it does not provide 3D Buildings data.

Question 15

Which of the following basemaps is not available through ArcGIS Online?

Accepted Answer

Land cover is not listed as a standard basemap option in ArcGIS Online. ArcGIS Online typically offers basemaps such as Oceans, Topographic, and Imagery among others, but Land cover must be accessed through other means or added as a separate layer from various sources.

Question 16

Digital Line Graphs of all states can be accessed via:

Accepted Answer

EarthExplorer is a website that provides access to a variety of geospatial data, including digital line graphs of all states.

Question 17

Which of the following is a source for obtaining Digital Raster Graphics?

Accepted Answer

Libremap is a source for obtaining Digital Raster Graphics, which are scanned images of USGS topographic maps.
