Coordinate Systems and Projections
This coordinate system uses latitude and longitude to locate positions on Earth.
What is a geographic coordinate system?
This is the process of collecting information about Earth’s surface without physically touching it, often using satellites, drones, or aircraft.
What is remote sensing?
GPS
What is Global Positioning System?
This editing setting helps features connect accurately by pulling vertices or edges together.
What is snapping?
This career field uses GIS to map roads, utilities, zoning, land use, and community development.
What is urban planning?
This coordinate system projects the curved Earth onto a flat surface using units such as feet or meters.
What is a projected coordinate system?
This type of image is collected from sensors on satellites, airplanes, or drones and is often used as a basemap or for land cover analysis.
What is imagery?
DEM
What is Digital Elevation Model?
These are the points that shape a line or polygon feature.
What are vertices?
This field uses GIS to map power lines, water lines, sewer systems, fiber routes, and service areas.
What are utilities?
This ArcGIS Pro tool changes a dataset from one coordinate system into another.
What is Project?
This process groups pixels into categories such as water, vegetation, roads, or buildings based on their spectral values.
What is image classification?
NDVI
What is Normalized Difference Vegetation Index?
This is the practice of placing text on a map so features can be identified clearly without clutter.
What is labeling?
What field is Carter in, outside of the classroom?
What is telecommunications GIS?
This problem can occur when GIS layers do not line up correctly because they use different or incorrectly defined coordinate systems.
What is a projection mismatch?
This elevation model represents the bare ground surface after buildings, trees, and other objects have been removed.
What is a DEM?
UTM
What is Universal Transverse Mercator?
This type of selection finds features based on where they are located compared to another layer.
What is Select By Location?
This field uses GIS to study habitats, wetlands, pollution, land cover, and natural resources.
What is environmental GIS?
This is the common geographic coordinate system used by GPS and many online mapping platforms.
What is WGS 1984?
This remote sensing technology uses laser pulses to measure elevation and create detailed surface models.
What is LiDAR?
LiDAR
What is Light Detection and Ranging?
This field type is used for words, names, descriptions, and categories.
What is a text field?
This field uses GIS to map hazards, evacuation routes, flood zones, shelters, and response areas.
What is emergency management?
