Editing Map Data

SurvPC Esri provides the ability to create and edit ArcGIS data to produce up-to-date maps.

Create and Edit the ArcMap Document from the ‘Map View’ screen

Create from the Map View screen

The Map View screen allows for points, lines, and polygons to be created and edited from the Map View screen. The associated attributes associated to a feature code can also be entered or edited from the Map View screen.

Create a Point from the Map View screen

To create a point in the Map View screen, select COGO → Create Points → Draw Locate Points (Sketch).

Create Points within the Map View screen

The object snap options (OSNAP) for point creation can be used. In this example, the freehand snap is used to allow selection of a new point directly from the map.

'Freehand' Snap Used to Pick New Point

Click anywhere on the map to create a new point. The user will be prompted for attributes based on the feature type. The feature type can be manually selected by double-clicking on the Feature dialog box.

Point Created

Double-clicking on the ‘Feature:’ dialog box will open the ‘Feature Manager’ screen. In this screen, the user can select which feature type the newly created point will be associated with.

‘Feature Manager’ screen

Once the feature type is double-clicked on, enter the remaining attribute data required. Click ‘Save’ to complete the point creation process.

Note: Once this point is created with an associated feature code, it cannot be augmented.

Create a Line or Polygon from the Map View screen

In order to create a line or polygon, first set the current layer to a polyline or polygon layer. Select the preferred layer and click on the ‘Current’ button. The layer selected will be part of a coding structure of which an MXD (or aliased MXD) will be associated. The MXD will have attributes assigned to it as part of the ArcMap schema. MXD information is located in the Survey and Remeasure Features with Attribute Data section of this manual. The attribute list may be viewed and edited from File → Feature Code.

Example Polyline Layer
Example Polygon Layer

Select Draw → Polyline → 2D (Sketch) to begin drawing a line or polygon.

Draw - Polyline - 2D (Sketch)

Select the preferred drawing method, here the freehand icon is used.

Freehand Polyline Draw

Proceed with line or polygon creation. A simple polygon can be created using the ‘Close’ command. A simple line can be created with the ‘End’ command.

Close Used to Complete Polygon

Once the line or polyline is created, the ‘Add GIS Data’ screen is shown where relevant GIS attribute data may be entered. The attribute list may be viewed and edited from File → Feature Code.

Add GIS Data for New Line or Polygon

Edit from the Map View screen

Features can be edited directly from the Map View screen, provided they are configured as selectable. If a feature is not selectable, then changes cannot be made from the Map View screen. A non-selectable feature can only be viewed from the Map View screen. A feature can be configured as selectable within the Feature Manager. Some Map Administrators preconfigure features as non-selectable to limit workflow complications.

Elements in the ArcMap document contain information beyond its specific location. This information is stored as GIS Attribute data. Element selection from the Map View screen will allow the user to view / edit GIS Attribute data.

Symbology is an important component in any map. Intuitive symbology relays information both quickly and effectively. The ArcGIS Symbol Library is widely known as a premier provider of intuitive map symbols. Different symbols originated from the ArcGIS Symbol Library will be included in an ArcMap’s schema. SurvPC Esri is able to seamlessly read, present, and change this symbology within the Esri Map’s schema.

Edit Attribute Data

A feature can be selected from the Map View screen and its associated attributes edited from the ‘Edit GIS Data’ screen. Selecting a point feature within a cluster of points will present the user with a point details screen where the user can further specify the intended singular point feature. Select Edit → Input/Edit Attributes to navigate to the ‘Edit GIS Data’ screen. Selecting a line or polygon feature will directly show the ‘Edit GIS Data’ screen.

Edit Existing Point Attribute Data

Click on a selected point feature to view the ‘Point Details’ screen. There may be multiple point features within the area of query; if so, select the point of interest and click on the details icon on the top ribbon.

‘Point Details’ (Multiple Points) screen
'Point Details’ (Information) screen

Within the ‘Point Details’ screen, select the ‘Edit’ button to view the ‘Edit Point’ screen.

Edit Point screen

Within the ‘Edit Point’ screen, select the ‘Input/Edit Attributes’ button to view the ‘Edit GIS Data’ screen.

‘Edit GIS Data’ screen

The ‘Edit GIS Data’ screen allows the user to change the attribute values of the selected map feature code.

Edit Point Symbology

Our ArcMap document is zoomed and panned to a specific section with several points.

Map View

Highlighted are 3 points, all currently in feature code (Layer) DTM_PUNT. Clicking on the left point shows the ‘Point Details’ screen.

Point Details for Selected Point

Clicking on the ‘Edit’ button opens the ‘Edit Point’ screen where the ‘Input/Edit Attributes’ button is found. Selecting the ‘Input/Edit’ button presents the ‘Edit GIS Data’ screen where the attributes of that point are shown. One of the attributes, found on page 2, is called ‘Soort DTM punt’ which will allow for the symbology to be viewed and edited. Currently, the point symbology is set to ‘Hoogtepunt’ (High Point), symbolized by a brown dot.

Edit GIS Data for Selected Point

The symbology can be edited by selecting the dropdown menu arrow on the right of the dialogue box. This dropdown menu will show the symbols included in the schema.

Available Attribute Symbols for Point within Feature Code

Selecting another point type will change the point symbol shown in the Map View screen. For example, selecting ‘Trap’ (second from the bottom) will change the point type and the symbol shown in the Map View.

Trap Selected
Point Type and Symbology Changed

The selected point within Feature Code DTM_PUNT now has the ‘Trap’ Symbology, as shown in the figure above. Using a variety of symbols to represent data point attributes clearly is a powerful tool, and is easily utilized using the steps shown above.

Edit Point Aliases

Point ID, Description, Elevation, and Codes can be aliased to match a preconfigured attribute within a feature. This requires coordination between the ArcGIS document Administrator and the Surveyor. Point ID, descriptions, elevations, and codes within data acquired in the field is usually stored outside the ArcGIS document. This data is stored in the CSCRD prefixed file automatically by default by SurvPC Esri.

If the ArcGIS document Administrator has an attribute where one of these data elements can be stored, they need to inform the Surveyor. The Surveyor, in SurvPC Esri, can then alias one of these data element to match the attribute name setup in the ArcGIS document.

As a simple example, the ArcGIS document Administrator may want to include the point description as an attribute within a Feature Class. They can create an attribute name ‘Field Description’ for this inclusion. The Administrator then informs the Surveyor of this intention. The Surveyor can then alias the default point ‘Description’ to ‘Field Description’. SurvPC Esri will then include this attribute within the database. When the database is subsequently opened by the ArcGIS document Administrator, this new ‘Aliased’ point attribute will be included automatically.

The Edit Point Aliases command can be found within the Points menu; click on File → Points to access this command.

Point List

Click on the ‘Aliases’ button to begin the edit point alias command.

Pick Point Info to set Alias

In our example, we are selecting the ‘Description’ field. The green check saves this change and allows us to continue.

Point Data Alias

The Surveyor can now see the Available Attributes table with the newly setup title as an alias option; ‘Field Description’ in our example. This option can be selected and click on the ‘Set New Alias’ button to complete the command. The data acquisition routine will not change for the Surveyor in the field, and this new attribute will be automatically included in the database.

Edit Existing Line or Polygon Attribute Data

Click on a selected Line or Polygon feature to view the ‘Edit GIS Data’ screen. This screen allows attributes associated with the selected feature code to be viewed and edited.

Edit GIS Data - Edit Line Attribute Data
Edit Line Symbology

Our ArcMap document is zoomed and panned to a specific section showing a line.

Map Zoom to Line

Clicking on this line will show the ‘Edit GIS Data’ screen, where the line attribute data is shown.

Selected Line Attribute Data

One of the attributes is the linetype (shown near the middle) with symbology, currently ‘Eiendomsgrense’. This line has a symbology property of a red line. Clicking on this attribute’s dropdown, we can see the different categories provided within the ArcGIS schema.

Linetypes Available

To change the line symbology to ’Bruksrettsgrense’, with a property of a yellow line, we select it and click ‘Save’.

Line Symbology Changed

Edit Lines and Polygons

Lines and polygons can be edited within the Map View screen. Some editing routines will be highlighted in this section.

Delete from the Map View screen
