| Geographic Modeling and Analysis | |||||||||||||||||||
| Introduction | |||||||||||||||||||
| This assignment is designed as further introduction capabilities of Arc View GIS. In the previous two assignment, we have been primary concerned with the process of database building and management. Now, in this assignment we will focus on the modeling and analysis capabilities of a GIS. Working with the data provided, you are asked to perform a geographic analysis application of your choice. In this assignment we use the background, interests and imagination to complete report on oneself. Study area we looked at as the same study area (Lombok) in the previous assignment number two. In this case we interested in the criteria, as we like especially. All digital data provided sent to my folder already from our lecturer. | |||||||||||||||||||
| Objective | |||||||||||||||||||
| 1) Establish a set of and/or constraints for an application of interest | |||||||||||||||||||
| -It will be helpful to review the data preview the data provide in the shared directory to determine if we application is possible 2) Import the data provided and convert to coverage (the use of an SML her may be helpful) if necessary 3) Project the imported data to a common map projection if necessary 4) Perform the analysis for our choice, incorporating the following analytical functions (The Arc View extension Geo-Processing Wizard must be loaded): |
|||||||||||||||||||
| -Query Builder and Calculator for re-format attribute information. | |||||||||||||||||||
| -Overlay (Intersect, Union) | |||||||||||||||||||
| -uffering (at least 1) | |||||||||||||||||||
| -Reclassification (Suitability classification, for example) | |||||||||||||||||||
| 5) Display the results incorporating Arc View's "hot-linking" functionality. | |||||||||||||||||||
| 6) Create a text file outlining some aspect of our analysis that will be displayed with our hot-link.Create a series of map layouts, Showing the steps that used while analysis (5 or more layouts), Incorporating | |||||||||||||||||||
| -A little | |||||||||||||||||||
| -A legend | |||||||||||||||||||
| -A scale bar | |||||||||||||||||||
| -Geo-referencing | |||||||||||||||||||
| -North arrow | |||||||||||||||||||
| -Relevant annotation (such as criteria listings) | |||||||||||||||||||
| -Key map 7) Automate the map layouts by using a simple Avenue slide-show script. |
|||||||||||||||||||
| -These layouts will form the basis for the presentation in the class | |||||||||||||||||||
| -Avenue scripts will provided | |||||||||||||||||||
| - Attach the scripts to the buttons of our choice to go forward and backward through our layout in sequence. 8) Create a chart to compare the output of our project/analysis for various scenarios. Be creative |

| Background Theory | |||||||||||||||||||
| Modeling activities can be of two forms: estimation and prediction models. Estimation designed to convert remotely sensed data into estimates of one or more physical parameters, may need to be implemented within GIS environment because the models may utilize a rang of data types. Predictive model will normally be implement within a GIS for the same reasons. GIS database was important for both the creation and implementation of many models. Model may be created as a result of statistic analysis, once the models have been developed then the GIS provides the numeric data necessary for implementation. | |||||||||||||||||||
| Models are used when it is more convenient or it is not possible to collect the information directly. The value in using a model is that it can be tested and manipulated more conveniently. The model is used to repeatedly perform analysis that test alternative scenarios, such as the effectiveness of an emergency evacuation plan in reply to different kinds of events, a model is used to answer question about what exists now or existed at some point in the past. A GIS these capability by means of its analysis functions. | |||||||||||||||||||
| The criteria in this case we like to establish Lombok Coastal Fisheries Development Center, so the area should near road, and we would like that near fisheries resource and also area of algae, and the area that select should be near port also, which can look in procedure. The GIS analysis function can be dividing in to four categories following: (1) maintenance and analysis of the spatial data, (2) maintenance and analysis of the attribute data, (3) integrated analysis of spatial and attributes and (4) Output formatting. Based on the definitions of GIS analysis and the fourth category function in the GIS analysis we can make the GIS model to get the results that we want. | |||||||||||||||||||
