The function project settings in metigo® MAP control the resolution and scale, the display of the project and the mapping elements.

You activate the window Project Settings via the Project>Project Settings... or Project>Project Presettings.... Both prompt dialogues which correspond each other with the slight difference that the first one is used for the currently opened project and the other one for any project that will be created in the future.

The Project Settings dialogue

Either the dialogues Project Preferences and Presettings for new projects will be prompted. They include four tabs: Project, View, Symbols / Mapping, Measurements.

The Project tab

Dialogue Project Preferences: tab Project.

On the Project tab, you can make settings to the image or object.

  1. At the Project Options section, you can change the resolution of the image data, the project scale and the Project UCS as well as the facing. The image files that have already been inserted will then be rescaled in the display. Note Note: The input fields are protected against undesired input. To modify the entries you have to press the button Change at the right first.
  2. At the Display Options section, you can select the display quality and make further settings for the display of your image. For image display you can choose between image files, layer settings and all greyscale values.
  3. You can activate image enhancement functions to process tonal range, brightness, contrast and sharpness of your image. Caution Caution: Any image enhancement might cause the loss of image information, such as clipping grey values at the start and end of the tonal range. Therefore, it is recommended to create a copy of the original image layers before starting image enhancement. You can do so simply by ticking the control box copy the image layer.
  4. At the Project Properties section, you find information about the project size (in terms of paper space) and the data volume which will be occupied if you save the images as RGB or Black & White (SW).

Areas of application and recommended project scale

metigo® MAP is used in various areas of documentation in restoration, conservation, buildinig archaeology and archeology. Depending on the application areas, different scales are used. The following table provides you with an overview of the required detail resolution for the various applications depending on image scale.

The View tab

The tab View contains functions for you to change the parameter for the zoom and the user-defined scale.

Dialogue Project Preferences: tab View.
  1. Enter here a user-defined scale 1:X for the default screen display. If you click the button IconZoom_X during mapping, this scale will then be applied.
  2. The scale factor you enter below Maximum Zoom (scale) applies to the zoom behaviour, the selected element or zoom window will be shown at the n-time magnification to the screen display 1:1:
    • Once you ticked the control box selecting element with double-click double-clicking any element at the tables on the tool window will apply that maximum zoom-factor and the selected element will be centered in the evaluation window.
    • Once you ticked the control box zoom window the maximum zoom factor will be applied to the window drawn with the mouse.
  3. Tick the control box automatic scrolling if you want to scroll automatically as soon as you are going to map beyond the margins of the evaluation window.

The Symbols / Mapping tab

The tab Symbols / Mapping contains various options for hatchings, drawings and CAD tools.

Dialogue Project Settings, tab Symbols / Mapping.
  1. Use the Scaling Factor for Hatchings function to scale the hatchings and adapt them to the current printout scale. The predefined symbol library has been created for a printout scale of 1:1. If you want to print your map on a scale of 1:25, you must enter 25 as scaling factor.
    The Scaling Factor for Image / Vector Symbols serves the same purpose as the above for hatchings.
    Note Note: If you select very small scaling factors, it might happen, that the drawing mode is slowed down, as to many points have to be processed. Orientate yourself at the size of your image point object.
  2. Select either symmetric or consecutive for the representation of the Line Type. The line pattern can be drawn symmetrically between two vertices. If you use the freehand mode for mapping, the distance between the points is too small to display a complete line pattern; a continuous line will be drawn instead. With consecutive selected, the line pattern will be drawn independently over all vertices.
  3. With the parameter Mapping Accuracy in Freehand Mode, you define the distance between two vertices of a freehand line. Depending on image scale and resolution, a value will be automatically suggested. Via the dialogue box Project>Image Planning, the size of a pixel can be calculated for resolution and image scale, this value can be applied.
    Note Note: Read more below Planning of Photography.
    If you map in the freehand mode and self-intersect the line, the area mapping will be interrupted and changes automatically into polygon mode. If the patch, created by self-intersecting, is smaller than the size defined in the input field Automatic Cleaning of Sliver Polygons, it will be deleted and the line will be continued from the intersection point.
    Note Note: Extremly small values for the mapping accurancy and the size of sliver polygons when mapping in freehand mode will have a negative influence on the run-time in large projects (compare below).
  4. Once you have ticked the control box Activate Snap Radius, the outline will be automatically closed as soon as the end of the line is approaching the other end of the line the preset
  5. The parameter Increment F5 [m] defines the increment for orthogonal displacement of mapping elements by using the function keys F5 and the four cursor keys.
  6. If the control box at the lower end of the dialogue is set hatchings and lines are drawn above solid and transparent fills.

The Measurements tab

The tab Measurements enables to set the font size, dimension unit and the decimal precision for your mapping.

Dialogue Project Settings: tab Measurements.
  1. The Font Size defines the character height for all dimension texts of area or line mappings. The shown [mm]s always refer to the character height for the printed edition at a scaling of 100%. You can also change the letter height in the course of project editing.
  2. You enter the scale unit in Unit and the number of decimal places behind the comma in Decimal Places. These settings apply to the currently edited view and can be changed in the course of the project. By default the calculation of the area will always be saved to the project correct to four digits behind the comma.
  3. In the section Other Settings for Measurements you can check several boxe
    • The option display units allows you to hide/show the units of measure for all dimension texts.
    • If you activate the option inquiry of single measurements, the width and height of the rectangle measured for area calculation will be displayed in a dialogue box (provided the rectangle function is used). You can confirm these values or include the values measured manually.
    • If you have checked the control box automatically adjust decimal places by dimension, the number of decimal places will be adapted when calculating areas and volumes.
  4. You can decide whether the bounding box for manual measurement input shall be calculated othogonal to the principal axis or aligned to the object.
