Answer 1

Answer:

Geographic Information System; Generic Information ... Geographic Information & Spatial Data Types. Q9. ... A ……………….. is a set of regularity spaced

Answer 2

Option a) Problem identification - Set layers - Analysis - Project Evaluation and c) Set layers - Project Evaluation - Problem identification - Analysis

• GIS known as Geographical Information System is an interdisciplinary field between geography and informatics and is listed as an application of geoinformatics.

• The concept uses software to access maps. By this method, we can analyze and achieve multiple objectives in one software.
• In simple words, it is the digital representation of real-world maps.
• We can set multiple layers in the maps like terrain, rainfall, crops, etc. in one map. Based upon the requirement, these filters could be used to analyze and interpret data.
• Option a) We can find a problem e.g. water pollution in a lake. We can set layers like industries around it, sewage water outlets in the lake, aquatic life forms in the lake, etc. Based upon the layers, the problem can be analyzed and the root of the problem can be found.
• Option c) We can make a map with several layers. Then the map is evaluated for possible problems. Once a problem is identified, we can analyze the map for the reasons from various angles.
