Buffers are terminologies that are used to refers to regions of storage that are used in holding information or data temporarily while being moved from one location to another. One of the most significant features of buffers is the determination of method parameter in determining how buffers are created. Buffers can be constructed in two basic methods being Euclidean and geodesic, where Euclidean is used in measuring the distance in a double dimensional Cartesian plane. They work best during the analysis of the distance on projected coordinate system features. For the geodesic buffers, their functionality comes during accounting for the earths actual surface. The geodesic features are created when considering input features dispersed. They are also used when the preservation of properties such as area during spatial reference of input features are of distorting distances.

During buffer creation, there are two major formats that are offered. The parsed data stream that is normally from the parse process. Parsed data refers to a data string transformed to a different set type. For instance, when it is received in HTML format, the parser will be able to convert it into a more understandable and easily to read type. The data stream is composed of parsed XML document and the header. While parsing the XML document, it is read and an interface provided for the user to access the documents.

5. Briefly discuss what Model Builder is, including the following topics in your discussion:
6. 1. Why Model Builder provides a graphic template
7. 2. What models created in Model Builder allow users to do
8. 3. What scripts are, and what they can be used for.

Geoprocessing workflows are built using programming languages that are known as Model builder. Spatial analysis is always documented and automated using geoprocessing models. It is used in creating and is modification of the models interpreted as a diagram linking process sequences together and geoprocessing tools, whilst utilizing one process' output as another process input. Some of the benefits of model builders include its ease of use in the creation and workflow Runnings. It also enables creation of tools that can be used in python scripting.

Graphic templates can be taken as features that have been created for particulate uses that are meant to save designers time and an able proper flexibility while editing. The graphic templates normally contain text colors and images that that are in most cases appealing to the eye (Esri, n.d). The graphic templates are used in illustration of tools and variable elements. Further more, the readability of the model is enhanced through the diagram properties, display properties and the pictures for the elements and label to document.

The models built by the model builder has many functions to the user. Some of the most specific functions include the following. They have the ability of selecting different layers by their attributes. Through the buffer, they can help create an area within 1500 feet distance around specified areas (Esri, n.d). They can also help the user erase the buffer area within the selected zones. Finally. They have the ability to intersect, in that they can help in overlaying the erase tool output with different layers hence ease in identification of areas meeting the needed criteria.
