Q1.
A LiDAR point cloud has returns with a point spacing of 0.5 m. A hydrologist needs a
terrain model to delineate first-order streams in a forested catchment. Which processing
sequence minimizes systematic error while preserving hydrologic connectivity?
A. Classify ground, interpolate to a 1 m DEM B. Classify ground, interpolate to a 0.5 m
using inverse distance weighting, then apply DEM using spline with tension, then apply a
a sink-filling algorithm. sink-filling algorithm.
C. Classify ground, interpolate to a 1 m D. Classify ground, interpolate to a 2 m
DEM using a triangulated irregular network, DEM using nearest neighbor, then apply a
then breach sinks using a carving algorithm. sink-filling algorithm.
Correct: C - Classify ground, interpolate to a 1 m DEM using a triangulated irregular
network, then breach sinks using a carving algorithm.
Rationale:A TIN preserves breaklines and hydrologic features better than grid interpolators,
and carving (or breaching) removes spurious sinks without altering the overall terrain, unlike
sink-filling which flattens depressions. IWD and spline can introduce artifacts, and
nearest-neighbor is too coarse for 0.5 m data.
Q2.
A geospatial analyst must produce a census tract map for a metropolitan area. The source
data are in NAD83 (2011) and the target is Web Mercator. Which transformation chain
preserves topological accuracy for overlay analysis?
A. Project to Web Mercator using a null B. Perform overlay in NAD83, then project
geographic transformation, then perform the final result to Web Mercator for display.
overlay operations.
C. Rasterize both inputs to a common grid in D. Use a datum transformation to WGS84,
Web Mercator, then overlay. project to Web Mercator, then overlay.
Correct: B - Perform overlay in NAD83, then project the final result to Web Mercator for
display.

AND Spatial DATA Learners GISP Actual Higher Education Geospatial Science Curriculum 2026/2027 Academic YEAR AND FOR Advanced GIS
Rationale: Overlay operations are best performed in a projected coordinate system with
minimal distortion, such as a state plane or UTM. Web Mercator introduces area and distance
distortions, and transforming to WGS84 may introduce datum shift errors. Rasterizing can
lose precision.
Q3.
A remote sensing analyst is comparing NDVI and EVI for a drought study. Which
statement correctly contrasts these indices?
A. NDVI is more sensitive to atmospheric B. EVI is more sensitive to soil background;
noise; EVI is preferred in high-biomass NDVI is preferred in dense vegetation.

C. NDVI is computed from red and D. EVI is always higher than NDVI; hence, it
near-infrared only; EVI also uses the is better for all land cover types.
thermal band.
Correct: A - NDVI is more sensitive to atmospheric noise; EVI is preferred in high-biomass
regions.
Rationale:NDVI is affected by atmospheric scattering and saturates in high-biomass areas.
EVI incorporates a blue band to correct for atmospheric aerosols and is designed to remain
sensitive in dense vegetation. EVI is less sensitive to soil background, not more, and it does
not use thermal bands.
Q4.
A spatial database contains parcel polygons. A query must return parcels whose area
exceeds the average area of parcels within their own county. Which SQL approach
correctly implements this without aggregation errors?
A. SELECT p.* FROM parcels p WHERE B. SELECT p.* FROM parcels p JOIN
p.area > (SELECT AVG(area) FROM (SELECT county, AVG(area) AS avg_area
parcels WHERE county = p.county); FROM parcels GROUP BY county) a ON
p.county = a.county WHERE p.area >
a.avg_area;
C. Both A and B are correct. D. Neither A nor B is correct.
Correct: C - Both A and B are correct.
Rationale:Both queries are logically equivalent: A uses a correlated subquery, and B uses a
join to a grouped subquery. Both correctly compute the county average and filter parcels. The
correlated subquery might be less efficient, but it is correct. No aggregation errors occur if the
county key is correctly used.
