  1. A fisheries manager is combining a benthic substrate layer with a water depth layer to identify spawning habitat. What GIS operation is being used?

    Answer: Map overlay (intersect/union)

    Map overlay operations like Intersect or Union combine multiple spatial layers to produce composite habitat classifications based on multiple attributes.

  2. What does NDVI (Normalized Difference Vegetation Index) derived from satellite imagery indicate in riparian buffer assessments?

    Answer: Vegetation greenness and density

    NDVI uses near-infrared and red bands to quantify vegetation density and health, useful for assessing riparian buffer condition.

  3. Which GIS approach is used to determine fish passage barriers by identifying stream reaches where gradient exceeds a threshold value?

    Answer: Longitudinal profile analysis with attribute queries

    Longitudinal profile analysis extracts stream gradient from DEMs and attribute queries flag reaches exceeding barrier thresholds for fish passage.

  4. In GIS telemetry studies, what statistical spatial method is most commonly used to estimate a fish's home range?

    Answer: Kernel Density Estimation (KDE)

    Kernel Density Estimation is the standard method for estimating home range utilization distributions from GPS or acoustic telemetry point data.

  5. A fisheries GIS dataset uses WGS84 as its datum. What does this primarily define?

    Answer: The reference ellipsoid and origin for coordinate measurements

    WGS84 (World Geodetic System 1984) defines the reference ellipsoid, origin, and orientation used to describe positions on the Earth's surface.

  6. Which GIS network analysis function would best help identify the fastest boat route to access remote sampling stations on a river system?

    Answer: Shortest path (least-cost) routing

    Shortest path or least-cost routing through a network dataset finds the optimal route between points based on travel time or distance impedance.

  7. What GIS metadata element is most critical to document when sharing a fisheries spatial dataset with other agencies?

    Answer: Coordinate reference system, data source, and collection date

    Coordinate reference system, provenance, and date are essential metadata so other users can correctly project, interpret, and assess the currency of the dataset.
