Module 4: Annotations and Basic Measurements

These flashcards cover essential terms and definitions related to geospatial data analysis, particularly focusing on annotations and measurements in GIS.

Geospatial Data Analysis

The process of interpreting and extracting insights from spatial data using specific tools and techniques.

Annotations

Visual elements added to maps or datasets to provide context, clarity, and interpretation of key features.

Orthomosaics

Aerial images processed to create a comprehensive, geometrically accurate representation of an area.

GIS (Geospatial Information System)

A system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.

2D Measurements

Assessment of horizontal dimensions in GIS, allowing users to calculate distances, areas, and perimeters on maps.

Ground Control Point (GCP)

Fixed points used to improve the accuracy of spatial data by aligning imagery with real-world coordinates.

Digital Surface Models (DSMs)

3D representations of a terrain surface, including all objects on it, created from aerial imagery.

Volumetric Tools

Instruments used to measure volume and capacity of structures or land surfaces based on spatial data.

Spatial Analysis

The technique used to evaluate the locations, attributes, and relationships of features in spatial data.

Client Benefit

The advantages or value provided to clients from the analysis, interpretation, and presentation of geospatial data.
