Cadastral Tools

Identify Tool

This tool shows attributes and relationships for features selected on the map. You can limit your selection layers, and explore the structure of the fabric, as well as any custom layers.

Basic Use

  1. click to start the tool
  2. Limit selection to a particular class of features.
  3. Use the mouse to click the feature you want to investigate.
  4. Use the selected features tree to navigate the relationships between points, lines parcels, line points and plans.
  5. Use the selected features tree to navigate between the fabric members, while viewing the attributes.

Tips

  1. You can first limit what surveys or plans are shown in the map using the Fabric Control.
  2. Use the Identify Tool Selection to limit what features types are selectable. Most often you will be selecting lines or parcels.
  3. The attributes/properties listing for features depends on your site's definitions in views and map themes. Some unnecessary attributes may be hidden depending on the view shown.

The Identify Tool is an ESRI ArcMap control, not a Seaconis control. It is a complex, powerful yet intuitive tool designed for general use with ESRI GIS layers. You can find complete documentation for its use either in ESRI documentation, or online. This document is focused on how it can be used within PlanTest.

Details

The Identify Tool combines map, hierarchical trees, and data tables allowing investigation of survey data, data models and properties shown in PlanTest maps. In PlanTest, we can use it to explore much of the jurisdictional Seaconis models, however it is a subset of these models that are represented in the ESRI parcel fabric data model for visualization.

PlanTest analysis uses internal proprietary data models augmented by adaptations for different jurisdictions. Analytic test results themselves are the best information for your site's data. However, the Identify Tool can assist you in understanding some of the basic models. More importantly, it is an excellent investigative tool to navigate surveys when problems are discovered by an analytic test.

Here are a few key points...

  1. The Identify Tool uses the ESRI Parcel Fabric data model for cadastral data.
  2. This data model has some peculiarities that are typically not useful to your jurisdictional PlanTest model.
  3. Parcels have a set of their own lines. This means each boundary between parcels, even in the same survey, is represent ed by two lines - even if it is a single boundary defined by two corners. So if you select a single boundary, you often get two lines, each showing a different owning parcel.
  4. Control points can be associated to a fabric point, or not. If your local fabric is not well coordinated, either by least squares adjustment, or by other means, there will be an observable offset from what you expect.
