The word "Lists" means the windows with coordinate lists and the windows with the list of the measured data. These two types of the window have many common features.
The lists are formed from the data written in rows. The first two rows are always the prefix and the point number, the others depend on the type of the window
Each point on the list is marked with an identifier after which the point can be found on the list, and it also contains other information, where some are for both the coordinate lists and the lists of measurements and some are specific.
The points are uniquely identified on the lists by a numeric or alphanumeric identifier. The meas-ured data list can contain an arbitrary amount of points with the same identifier, but one identifier at the most can be on the coordinate list.
The numeric identifier is formed of two parts - the prefix and the actual point number. The prefix can be at most 8 digits, while the actual point number has at most 4 digits. Therefore, the complete point number can consist of 12 digits at most.
If the inserted identifier doesn't comply with the requirements for a numeric identifier (contains letters or other nonnumeric characters, or is longer than 12 digits), it will be understood as an alpha-numeric identifier. The only limit for the alphanumeric identifier is that it must not be longer than 16 characters. If longer, the identifier will be cut from the right.
Numeric identifier have priority over alphanumeric identifiers, therefore each identifier which can be interpreted as a 12 digit point number is implicitly understood as numeric. If you want the identifier to be qualified as alphanumeric regardless of its appearance, it must start with the character ' (apostrophe) or be closed in quotation marks. This character will not be part of the identifier as it will be omitted on input.
This item contains the date when the point was created on the list, in the case of the points imported from older versions of the GROMA system, this data isn't filled.
Here the information on the last point modification is saved - e.g. editing, bulk change, etc. From this data can be determined when the point information was last changed.
The point code contains up to a 20 character description of a point, which can be used, for example, for storing the descriptive point information, code for automatic connection, name of the graphic cell, etc. The code can contain arbitrary alphanumeric characters. The code can be converted to a description, using a code table, which is no longer limited by 20 characters.
One-character data, which can be used for description of the point quality (e.g. for the work at the Land Registry Office the numeric codes for the point quality characteristics are used).
Type of a point is a one-character alphanumeric data similar to the quality code, which can be used for further specification of the points' information (this data can be used for example for a selection from the lists).
Point coordinates in the selected system of coordinates. The coordinates X and Y are required, the coordinate Z is voluntary.
Another four additional numeric data which can be used for example for the depth of the bedding of the engineering nets, for a second pair of point's coordinates, etc. Such information can be arbitrarily named and you can define how they will be displayed (number of characters, number of hundreds). The data can be used for marking the points, and they can be change by a bulk change.
A horizontal angle (direction of the measurement), is typically overtaken during the field book import. The angle, as well as other angle data from the GROMA system, is saved in the system in radians, and is displayed on all the reports according to the set angle units. When entering the angle data, the appropriate angle units must be set up. You can change the angle units in the configuration of the GROMA system at any time, and on all reports the angle data will be displayed using the set angle units.
The distance between the station and the measured point. This distance is, in the GROMA system, always horizontal. It you measure (or enter from a keyboard) diagonal distances, they will be automatically reduced to horizontal in the input in the field book, therefore there are always only horizontal distances displayed in the windows with lists, and also all the calculation jobs presume the input of horizontal distances. The condition for the automatic reduction is the input of a zenith distance or the, without which cannot be performed the recalculation to horizontal.
In addition, the distances are during automatically adjusted by the measurement the import from the field book (influence of the elevation and cartographic distortion).
The zenith distance (the angle measured from the vertical). This data is used for height calculations and for detection of the measurement in II. position.
Some instruments automatically recalculate the measured zenith distance to the registered elevation during the registration. Within processing the field book the registered zenith distances can be recalculated to the elevation.
In the height calculations, either a zenith distance or elevation can be entered. If both are entered, the elevation has priority.
Stationing (horizontal distance on the measuring line from the start of the line to the foot of the perpendicular to the determined point).
