✍️ Sample GISP Questions & Answers
1. Who is the leading company for GIS business applications?
ESRI is the leading company for GIS business applications. They have established themselves as a global leader in the field of Geographic Information System (GIS) technology. ESRI offers a wide range of GIS software and solutions that are used by various industries and organizations worldwide. Their products are known for their advanced capabilities, user-friendly interfaces, and comprehensive data analysis tools. ESRI's dominance in the GIS market, along with their continuous innovation and commitment to customer satisfaction, has solidified their position as the leading company in this field.
2. What does Dilution of Precision (DOP) measure in GPS surveys?
DOP quantifies how satellite geometry affects positional accuracy — a low DOP value (closer to 1) indicates favorable satellite spread and more precise positioning.
3. Which agile project management framework uses fixed-length iterations called sprints, typically lasting 2–4 weeks, and is increasingly applied to GIS software development?
Scrum is an agile framework that organizes work into time-boxed sprints, enabling iterative delivery and continuous improvement in software and GIS development projects.
4. What is the minimum number of GPS satellites required to calculate a 3D position fix (latitude, longitude, and elevation)?
A minimum of four satellites is required for a 3D GPS fix — three to solve for the three position coordinates and a fourth to eliminate clock error in the receiver.
5. Which technique allows a GIS technician to collect GPS data along a linear feature such as a trail or road centerline?
Track logging continuously records GPS positions at set time or distance intervals as the receiver moves, creating a series of points that define a linear or areal feature's path.
6. Which cost estimation technique uses historical data from analogous projects to estimate the cost of a new GIS project?
Analogous estimating uses actual costs from previous similar projects as the basis for estimating the current project's cost.
