2015-S1 GGH3703 Feedback on Assignment 1 Assignment 01 required students to conceptualise a spatial problem and discuss how they will represent reality in a GIS. The purpose of the assignment was to make students aware of how real life “things” (phenomena) will be mapped and the implications of how we represent features and phenomena. Question 1.1: Identify a spatial problem Most students were able to discuss and describe what makes a problem spatial. Problems are spatial in nature when the features

“INTRODUCTION” Geographic Information System (GIS) is a computer based information system used to digitally represent and analyze the geographic features present on the Earth ’s surface and the events (non-spatial attributes linked to the geography under study) that taking place on it. The meaning to represent digitally is to convert analog (smooth line) into a digital form. "Every object present on the Earth can be geo-referenced"‚ is the fundamental key of associating any database to GIS

cultural and physical features. Scale- the relationship between a map’s distances and the actual distances on Earth. Space- the physical gap between two objects. Connections- relationships among people and objects across a barrier of space. Cartography- the science of map-making. -Earliest surviving maps are from Babylonian clay tablets‚ (c. 2300 B.C.) -Aristotle was first to demonstrate that Earth

IMPORTANT DEFINITIONS DEFINITIONS FROM TOPO MAPS REPRESENTATIVE FRACTION (RF): It is the ratio between the distances on the map to its corresponding distance on actual ground. The RF on this map is 1:50‚000. 2. SCALE : Scale is the ratio between the distance of any two points on the map and the actual distance of the same points on the ground. The scale of the given map extract is 2 cm: 1 km or 1:50‚000. 3. CONTOUR: Contours are imaginary lines drawn on maps‚ joining all places with

Manipulating data can distort the desired results on a thematic map. A- Define what a choropleth‚ dot‚ and symbolic map is and how they measure intensity B- Discuss how each map can distort a map when you manipulate data for each. C- Discuss how a choropleth map can give false impressions when using a smaller (distance) scale versus a larger (distance) scale D- Discuss how changing the natural breaks to quintiles can give false impressions on a choropleth map.

MS 217 Dennis Borzakov Class 723 January 15‚ 2013 Problem HOW IS A TOPOGRAPHIC MAP MADE Hypothesis I think that to make a topographic map you have to see the form of the object from up top. To do this you need a satellite image. These images are called aerial photographs. Using elevation calculators and ground measures cartographers then make topographic maps.
