How to write the syntax on Select by Attribute when you want to find "area" less than 1000 is
“Area” < 1000
“Area” <= 1000
“Area” > 1000
“Area” >= 1000
How to write the syntax for Select by Attribute when you want to find "area" less than 1000 and more than equal to 500 is
“Area” < 1000 AND “Area” >= 500
“Area” < 1000 OR “Area” >= 500
“Area” < 1000 AND “Area” > 500
“Area” < 1000 OR “Area” > 500
How to write the syntax for Select by Attribute when you want to search for “Kecamatan” starting with B is
“District” LIKE 'B'
“District” FIND 'B'
“District” FIND 'B%'
“District” LIKE 'B%'
How to write the syntax for Select by Attribute when you want to search for “Kecamatan” Dramaga and Ciampea is
“Kecamatan” = 'Dramaga' AND “Kecamatan” = 'Ciampea'
“District” = 'Dramaga' OR “Kecamatan” = 'Ciampea'
“Kecamatan” OR 'Dramaga' = “Kecamatan” OR 'Ciampea'
“Kecamatan” AND 'Dramaga' = “Kecamatan” AND 'Ciampea'

Georeferencing is the process of equating the coordinate system from map to image, from image to image, or from the map to map.
True
False
A transformation is a form of step in the process of making vector data or in other words turning a map into an image.
True
False
Registration is an equalization of the position of one image with another image or image with another map by ignoring the coordinate system of the image/map in question so that different pixel positions can be compared.
True
False
Raster data is data that displays the spatial side of the earth in the form of pixels (picture elements) that form a grid/plot and are generated from remote sensing. In raster data, the resolution depends on the pixel size. The smaller the size of the earth's surface represented, the higher the resolution.
True
False
Geometric correction is the repositioning of the pixel position in such a way that the transformed digital image cannot see the image of the object on the earth's surface recorded by the sensor.
True
False
Vector data is data that displays spatial patterns in the form of points, lines, curves, or polygons.
True
False
Vector data is represented on:
Node
Arc
Line
Polygon
Point
The following are included in the external errors in geometric errors are:
Changes in altitude of rides and satellites
Change the position of the vehicle to the object
Earth Rotation
Earth's curvature
The map projection system is a system designed to represent the surface of a curved plane or spheroid like earth on a flat plane.
True
False
The following are the steps for doing the correct digitization:
Create a new shapefile -editor start editing- set the feature type and spatial reference- start digitizing
Editor- Start editing- create a new shapefile- set the feature type and spatial reference- start digitizing
Editor- Start editing- set feature type and spatial reference- create new shapefile- start digitizing
Create a new shapefile – set the feature type and spatial reference – editor- start editing- start digitizing
