BIL2BMP

- BIL/HGT to BMP Converter -

by Yuzuru Jewell(KANAE PROJECT)

This program reads binary altitude map(BIL) and outputs a texture and height map in bitmap form. This program can also read the data of SRTM3 data(HGT) and the data of The Global Land One-km Base Elevation (GLOBE) Project. If there is a HDR file of the same name, this program automatically read Byte Order, Colomns, Rows, and Missing Flag. When there is not HDR file, this program specifies them in a dialog. Byte Order is chosen from Signed 16 bit little-endian and Signed 16 bit big-endian. A texture specifies a color using conversion table of the height and color of BIL2BMP.txt.

Install

There is no installer.

Uninstall

You can uninstall only by deleting the file called BIL2BMP.exe.

1) Load BIL/HGT
The 9 control points for editing the selected area are displayed.

Software reads the binary file of height information.
It is the arrangement of little_endian of smallint, or big_endian.
The unit of height is meter.
When there is a HDR file of the same name, you can use the file.
HDR files are the following structures in a text.

--
data_byte_order          = little_endian or big_endian
number_of_rows           = NNN
number_of_columns        = NNN
elev_m_missing_flag      = -NNN
--

A space is disregarded. "NNN" is an integer. Other value is not used.
The maximum of Colomns and Rows is 1201.
If there is not HDR file, this program specifies them in a dialog. If you load HGT files, Setup Dialog was shown. The parameters are set automatically. Please click the OK button, if it is as expected.
If there is not HDR or HDT file, this program specifies them in a dialog.

2)Save BMP

This program outputs two BMP files. They are the texture file (TX file) which added "-tx" to the file name inputted into the dialog, and the height map file (HT file) which added "-ht".
TX file outputs a texture file from BIL using the conversion table of a color and height of BIL2BMP.txt.
HT file is the monochrome picture which carried out smoothing by the width which specified the height information on BIL and which was optimized from 0 to 255. White is high and black is low.

texture file
height map file

If you specify the range by the drug of a mouse, software changes the specified range. If you do not specify the range, software changes all the ranges.

3)Smoothing

When outputting above-mentioned HT file, the width which carries out smoothing is specified. The left is small and the right is large.

4)BIL2BMP.txt - Structure of the conversion table of a color and height.

It is a TAB pause.
