Import Culture: Other Parameters

Use the Other Parameters page to provide additional import parameters for specific file types. The options on this page will be different depending on the file type you are importing. This page only available for the following file types:

Landmark Metafile
DXF File
Shapefile
Columnar ASCII

Options when Importing a Landmark Metafile

Honor Polygon Fill Flag: Frequently Landmark Metafiles have the polygon fill flag incorrectly set. Even though polygons should only appear as outlines the flag indicates they should be filled. If you have polygons that are actually filled, setting this flag will allow you to import filled polygons correctly.

Text Scale Factor: Sometimes Landmark medievalist contain incorrect scaling parameters causing text to appear either very large or very small. Make this value larger than one to increase the resulting text, or make it less that one but greater than zero to decrease the size of the resulting text.

Options when Importing a DXF File

Line Width Scale Factor: Sometimes DXF files contain line widths in world coordinates. If they do, when imported it can make lines appear very thick. Use a value of 1 if the line widths are not in world coordinates, but use a value around 0.018 to have them appear correctly after import. (This scale factor assumes that the data was output at a map scale of 1:50000)

Options when Importing a Shapefile

Import contour field: Specify one numeric value that will be the contour value associated with a line or polygon.

Import text fields: Select the labels contained within the DBF files that you want associated with the culture layer. These labels will be generated along the line or within the polygon, depending on the shape type. Double click on an item to move it to the Selected list, or use the selection arrows.

Options when Importing a Columnar ASCII File

Define Columns: Define the columns within the columnar ASCII file. At a minimum, you need to define columns for X and Y, or latitude and longitude. The Output Shape selection determines how these points are joined.

Layer Name: The name of the culture layer. When a columnar ASCII file contains a single culture layer, you do not need to define this column. Instead, name the file on the Import Layers page of the wizard. When a file contains multiple layers, this must be defined, or else all of the layers will be merged into a single layer.

Segment ID: Define this column when a single file contains multiple objects identified by an ID number. If you define this column, the Output Shape selection defaults to Treat as Closed Polygons.

Text: A text label associated with a data point.

X: The X coordinate or longitude value. When you are defining longitude, make sure you turn on Convert from latitude/longitude To XY on the Coordinates page of the wizard.

Y: The Y coordinate or latitude value. When you are defining latitude, make sure you turn on Convert from latitude/longitude To XY on theCoordinates page of the wizard.

Z: The Z value associated with the data point in time or depth. This can represent the level of a contour, or the time or depth of a microseismic event. The Z values can be converted between time and depth using a single velocity curve.

Extra Columns: Enter a name for an addition column. This is used when you are importing microseismic data to define time (HH:MM:SS), stage, amplitude and magnitude data.

Convert Z Value: Turn this on if you want to convert the values in the Z column between time and depth using a single velocity curve. Click to open the Convert Z Value dialog box. From here you can select a well, and specify the velocity curve to use, as well as select the direction of the Z value conversion - time to depth, or depth to time.

Output Shape

Specify whether the points in the files will be treated as separate objects, or joined into one object.

Treat as single points: Every point in the file is considered to be a separate object. Use this option when you are importing microseismic data.

Treat as closed polygons: Every point in the file will be joined to create a closed polygon. When you define a Segment ID, the points in each segment will be joined to create a closed polygon.

Connect points into lines: Every point in the file will be joined to create an open polygon. To create a closed polygon using this option, the last point in the file must match the first point in the file exactly.
