TUTORIAL : Dataset Creation

A dataset is a set of data necessary to reproduce terrain in arcAstroVR and consists of terrain data, object data and dataset.txt. For information on creating terrain data, please refer to Creating Terrain Data.

Description of dataset.txt

In the data set, write the location and installation information of the data.
Use the ENTRY = SETTING format, one item per line.
Use # for comment out.

Each setting entry is described below.

Basic Settings
location	Title name of the data (string)
country	Country name of the data (string)
timezone	Time zone (HH:MM: -12:00 to +13:00; +0:00 if not set)
date	Date setting at start (yyyy/mm/dd: if not set, the current time is set)
time	Time setting at start (HH:MM:SS: If not set, the current time is set)
mesh	Set mesh resolution (enter the value set for narrow-area terrain resolution in the terrain4arcAstroVR plug-in for QGIS)
type	Set the coordinate system to be handled (WGS84, JP01~19, or UTM01~60; the two-digit number after JP or UTM indicates the zone number).
center	Set the coordinates of the terrain center point (set the center coordinates in the coordinate system set by type: longitude and latitude (°) for WGS84, Y and X coordinates (m) for the specified zone number for JP, and E and N coordinates (m) for the specified zone number for UTM).
height	Set the height of the ellipsoid at the terrain center point (m) (if the geoid height is not included in the terrain4arcAstroVR plug-in for QGIS, set the elevation value)
avatar	Data file name of the avatar (Unity Humanoid model)

Marker Settings(The numbers in [] are marker numbers; numbers are assigned in order from 1 to the next. There is no limit to the number of objects that can be registered.)
marker[1].name	Marker name (string)
marker[1].origin	East coordinate, North coordinate (float : degree or m) (required)
marker[1].height	Ellipsoid height (or elevation value) (float : m) (required)
marker[1].color	Color designation (hex color value)
marker[1].visible	Show/hide marker (boolean: true or false)

Auxiliary line Settings(The numbers in [] are auxiliary line numbers; numbers are assigned in order from 1 to the next. There is no limit to the number of objects that can be registered. If end_marker is specified, the line will be drawn between start_marker and end_marker. If end_marker is not specified, a supplementary line is drawn starting from start_marker in the direction of the angle specified in angle. Multiple angles can be specified by separating angle with ,.)
line[1].name	Auxiliary line name (string)
line[1].start_marker	Marker number of the starting point (integer) (required)
line[1].end_marker	Marker number of the end point (integer)
line[1].angle	Auxiliary line azimuth starting from the starting point (float : degrees; multiple values separated by , are allowed)
line[1].color	Color designation (hex color value)
line[1].visible	Show/hide auxiliary line (boolean: true or false)

Object Settings(The numbers in [] are object numbers; numbers are assigned in order from 1 to the next. There is no limit to the number of objects that can be registered.)
dataset[1].name	Object name (string)
dataset[1].file	Object data file name (string) (required)
dataset[1].origin	East coordinate, North coordinate (float : degree or m) (required)
dataset[1].height	Ellipsoid height (or elevation value) (float : m) (required)
dataset[1].rot_E	East axis rotation at object origin (float: degrees)
dataset[1].rot_N	North axis rotation at object origin (float: degrees)
dataset[1].rot_H	Vertical axis rotation at object origin (float: degrees)
dataset[1].scale	Magnification of object (float : times)
dataset[1].start	Existence start year (integer)
dataset[1].end	Existence end year (integer)
dataset[1].visible	Show/hide object (boolean: true or false)
