Skills check-in
Now that you have explored these concepts, it is time to check in! This is not an exhaustive list of topics that are covered on the exam, but it references the types of tasks a qualified candidate should be able to perform. If there is anything you cannot confidently do, review those concepts until you can.
I can:
Identify data formats for surfaces, or multispectral applications, simple feature, multidimension, LAS data, external formats (CAD).
Compare a variety of geodatabase or external storage types (for example, elevation raster, LAS datasets, terrain datasets).
Create a mosaic dataset from raster data or LAS data.
Create derived raster products.
Create and maintain attachments.
Given a task, determine the data, settings, and parameters for creating a complex dataset
ArcGIS supports the creation of complex datasets that can be used to perform network analysis on both transportation and utility networks. Networks can be used to help plan routes for a delivery fleet or to calculate vehicle drive times while including impedance factors such as street direction and traffic volume. This section describes two ways to use networks in ArcGIS. This skill consists of two parts: (1) network datasets and (2) geometric networks.
Network datasets
Network datasets are used to model networks that allow bidirectional travel or facilitate travel by agents who can make decisions about how to travel across the network (such as a delivery driver in a transportation network). After a transportation network has been modeled, it can be used to optimize route planning and streamline business processes. For example, a parcel shipping company might use a network dataset and tools in the ArcGIS Network Analyst extension to calculate the least-cost path (where least-cost is defined as shortest travel time) from a warehouse to a customer’s home.
Network datasets are made up of point and line features, known as network elements, that define the physical characteristics of the network. The topological relationships of these features are enforced by logic that is built in to the network dataset. These network elements establish connectivity and control navigation over the network. When you create a network dataset, you identify line and point features that will create your network’s basic structure as edges and junctions. Network datasets may also include turns, which are used to model restrictions in the network. The elements are then used to model and describe connectivity. Connectivity tells the network how your edges and junctions are formed and describes which network sources interconnect. In a network dataset, the connectivity model is discovered on demand and is
