A layer without a spatial reference or coordinate machine is the primary layer introduced to an
Untitled.Mxd (new map). What will ArcMap assign to the facts frame as a spatial reference?
A) the coordinate gadget can be defaulted to WGS 1984
b) the coordinate gadget might be inherited from the closing opened map file (.Mxd) on the
consumer's pc
c) the coordinate system may be set to Unknown till the coordinate system is manually set for
the statistics body
d) the coordinate gadget will stay unknown till another layer with a acknowledged coordinate
device is brought to the records frame - ANS-c
A scientist investigating the unfold of a plant disease has a characteristic class of study regions
and every other function magnificence of 1 meter x 1 meter quadrants used to gather plant
samples. Each take a look at vicinity carries five sample quadrants. The scientist wishes to
associate the 2 attribute tables in a manner that if a look at vicinity is moved or circled, the
sample quadrants in it are moved or rotated as nicely. Which form of desk affiliation could you
use? (7-2)
a) simple courting elegance
b) easy relationship elegance with backwards messaging
c) composite relationship elegance
d) composite dating magnificence with forward messaging - ANS-d
After you added the first layer to a facts frame, you find out that your map needs to be in a
exceptional coordinate machine than the primary layer. What is a valid approach for changing
the spatial reference of the statistics frame?
A) in ArcMap, proper click the statistics frame and pick out Set Spatial Reference
b) in ArcMap, proper-click the facts body and choose Properties and use the Coordinate System
tab
c) in ArcCatalog, proper-click on the map report and choose Properties to change the
coordinate gadget
d) in ArcMap, use the Define Projection tool to change the coordinate machine - ANS-b
For each of the subsequent eventualities, determine which type of coordinate device to use:
a=geographic, b=projected
, 1) You want to acquire samples of ozone concentrations in exclusive towns worldwide at
different instances of the year.
2) You need to use climate records in a map so as to be used to devise the most efficient
aircraft routes among one-of-a-kind continents of the arena.
3) You need to make a quick map to evaluate if a dataset has a enough quantity of spatial detail
(scale) and make sure it covers your examine region. - ANS-1) a (b/c just storing GPS point
locations?)
2) b (b/c navigation?)
three) a (quick exploratory map = geographic adequate)
For every of the subsequent eventualities, decide which type of coordinate gadget to apply:
a=geographic, b=projected (5-1)
1) You want to make a thematic map of populace density in distinctive international locations
2) You need to create the boundary traces of land parcels from the bearings and distances of
supplied survey measurements.
Three) You want to shop the epicenters of earthquakes in a geodatabase that may be accessed
through a internet site that allows users to download the data. - ANS-1) b (for pop density,
should display real region)
2) b (for correct geometry)
three) a (customers can undertaking after downloading)
The GCS of your information frame is NAD 1983 and GCS of the incoming vector data is WGS
1984. What do you need to do?
A) outline the coordinate machine of the information
b) observe a geographic transformation
c) undertaking the information
d) use projection at the fly - ANS-b
The GIS department of a town maintains a parcels table, and the assessor's department keeps
an Excel desk of tax information for each parcel. Each parcel document corresponds to
precisely one record of tax statistics. Once a year the GIS branch needs to feature the up to
date tax records to the parcel function magnificence attribute table. Which type of desk
association could be most suitable?
