GIS Exam 2 with 100% Correct
Answers
Data that have some forme of spatial or geographic reference that enables them to be
located in 2D or 3D space - ANS-Spatial Data
A set of mathematical/statistical tools used to find order and patterns in spatial
phenomena - ANS-Spatial Analysis
Is aimed at identifying/describing patters and identifying/understanding the process -
ANS-Spatial Analysis
Refers to various levels of spatial regularity, which includes local clusters of points,
global structure of a surface, and so forth - ANS-Spatial Pattern
3 objectives of spatial analysis - ANS-1. to detect spatial patterns that cannot be
detected by visual analysis 2. to confirm wheter a spatial patter found in visual analysis
is significant (nonrandom) 3. To learn limitations of statistics
What is the spatial analysis also known as? - ANS-spatial statistics
Location where the subsurface has been drilled and are defined as 2D point features -
ANS-Well
True or False: Well features are not related to aquifers? - ANS-False: They ARE related
to aquifers
The region draining into a river, river system, or body of water - ANS-Watershed or
drainage basin or catchment
Fills in sinks or cuts off peaks creating a new grid with no drainage errors - ANS-Fill
routine
3 places where watershed terminate? - ANS-ridgelines, uphill sub-basin boundaries,
and edge of the raster
Representation of data from geologic maps - ANS-Geology, boreholes,
hydrostratigraphy, simulation
Description of well attributes and borehole data - ANS-Boreholes
, 2D and 3D description of hydrostratigraphy - ANS-hydrostratigraphy
Representation of time varying data - ANS-Temporal
Representation of groundwater simultation models - ANS-simulation
a cartographic product that portrays information about the geologic character of a
specific geographic area - ANS-Geologic map
3 geology components - ANS-point feature, line feature, areal features
any soil or rock unit or zone which by virtue of its hydralic properties has a distinct
influence on the storage or movement of ground water - ANS-hydrogeologic units
2D polygons defining boundaries of hydrogeologic units - ANS-GeoArea
can store hydraulic properties such as transmissivity, conductivity, and specific yeld -
ANS-GeoRasters
Darcy's Law - ANS-Vg=KS/Theta
An object-oriented scripting laguage for Geoprocessor that can be used in all of ArcGIS
- ANS-Python
Three places you can write Python code - ANS-PhytonWin, PyScripter, Python window
in ArcGIS
How do you run Python script? - ANS-double click or cmd prompt
The most fundamental spatial objects in GIS - ANS-Points
Quantitative measure that indicates the degree of clustering - ANS-Point Pattern
Analysis
Used to pull information out of GIS as a question and replies as spatial and attribute
information - ANS-Query
Any GIS operation that creates new data - ANS-Geoprocessing
3 types of geoprocessing tools - ANS-Analysis, data management, General
5 types of analysis tools - ANS-buffer, extract, clip, overlay, intersect
2 types of data management tools - ANS-generalization, dissolve
2 types of general tools - ANS-append, merge
