Common Properties of Reference Layers

General

The menu that displays the general properties of the reference. The General menu is common for all references, even in different formats located under References / Categories.

OptionExplanation
NameName of the reference.
TransparencyUsed to give transparency to reference objects.
PrintableUsed in active state for output of the reference.
Snatch ObjectEnsures that the recorded objects in the references are catchable.
Influence Project LimitWhen the find limit operation is performed in the project, the reference limits are taken into account.
Visible Areas

Visibility fields and references are masked. Only a part can be made visible or invisible. This feature works well in situations where the layout edges, such as raster references, should be invisible. Visibility fields are created with the Field Selection Tool (?) .

+ : Preferred to add the visible field to the reference according to the class shown.

: Preferred to add the reference invisible field according to the class shown.

! : Preferred to cancel the defined visible or invisible area.

Load ReferenceIt allows the layer structure of the loaded file to be added as reference to Netcad layers. The 'Load Reference' feature is available only on CAD and Grid references.
Find Table LimitsUpdates Spatial reference table limits
Read Original Layer İnformationUsed to update CAD reference file information. The changes made on the file added as a reference on this page are displayed on the screen.
Transformation

Dynamically scrolls, rotate, scales, and transforms matrix operations on the reference file without changing the original data.

  • Slide: Allows to move the selected point of the reference to a different coordinate.
  • Rotate: Used when the selected constant point of the reference is rotated.
  • Scale: The reference is scaled according to the magnification rate given to the selected point on the reference.
  • Matrix: Used to convert the data contained in any coordinate system to a different coordinate system. For this, the conversion process is performed by entering the desired matrix values from the following menu. Matrix operation; frequently used in transforming reconstruction coordinates into cadastral coordinates.

    For example; The conversion of the local layout system to the country coordinate system by the transformation matrix coefficients can be shown. Based on the transformation, the known matrix coefficients (a, b, cy, cx) for the region are transformed into the country coordinate system.

Time IntervalThe reference file of the  Time Traveller module is used to enter date information.

Projection

The section used for definin Projections for each reference file.

With the projection definition, the reference is automatically displayed on the project projection (on-the-fly-projection). On this count, a different projection (geographical, Ankara slice, Lambert et al.) can be observed on the project.

If the projection of the reference is undefined; will always appear on their own coordinates.

 

Icon

Some references have their own projection information and may not allow users to make changes.

Icon

In some cases, the conversion rate between two different projections can be major. The amount of error is reported in this tab. If the error is high, the accuracy of the operation of the digitization done on the reference etc. is reduced.

More information about projection can be found in the Projection Settings (?).
