Magliacane (11-Apr-09): + +* Introduced one arc-second high-resolution versions of SPLAT! + (splat-hd) and the srtm2sdf utility (srtm2sdf-hd) to permit + detailed topographic and RF signal analyzes based on SRTM-1 + digital elevation models. + +* Introduced a new configure script that generates the appropriate + MAXPAGES parameter prior to compiling SPLAT! based on user + interaction at configuration time. + +* Added transmitter EIRP, estimated received signal power level + (in dBm), estimated received signal power density (in dBW/m^2), + and received signal power density to Path Analysis Reports. + EIRP can also now be expressed as dBm in place of ERP in + Watts in .lrp files. + +* Added a new mapping mode that plots contours of received signal + power levels in dBm using the new -dbm option. New .dcf files + control the color scheme of the plotted contours. + +* The function of the -db option has been expanded to serve as a + contour threshold limit for all three mapping modes (path loss, + signal strength, and signal power level). + +* New -ano and -ani (alphanumeric output and input) options have + replaced the -plo and -pli (path loss output and input) options, + and can contain either path loss data (as before), field strength + data (new), or received signal power level data (new). Path loss + figures in .ano files ignore the effects of transmit antenna + pattern, while field strength and received signal power levels + take antenna pattern into account. + +* Uniform ground clutter height can now be specified using the new + -gc switch. + +* Several bugs in SPLAT!'s UDT file handling were fixed. + +* Bugs affecting the operation of the -f switch were identified + and fixed. + +* The reported field strength and the corresponding voltage induced + across the receive antenna in Path Analysis Reports were found to + be 2.14 dB too low. The cause was identified and fixed. + +* Some modifications were made in coding and scripting in response to + changes that have occured in the latest versions of gcc and bash. + +* The documentation was updated to reflect all the improvements. + + +---------------------------------------------------------------------------- + +Release 1.2.3: +By John A. Magliacane (30-Jul-08): + +* Fixed a problem that sometimes caused SPLAT! to hang indefinitely + when reading some cartographic boundary files on some platforms. + +* Fixed a problem introduced in v1.2.2 that sometimes caused black + horizontal and/or vertical dotted lines to appear in path-loss + and signal strength contour plots. + +* The UDT file switch was described as -udt in the documentation, + but recognized as -u in SPLAT!. SPLAT! was modified to reflect + the documentation. + +* The -R option can now increase (as well as limit) the .ppm image + size when generating topographic maps. + +* Dots ('.') are now permitted in the base of filenames passed to SPLAT! + +* Further improvements in accuracy were made to both SPLAT! and the + srtm2sdf utility. Users are encouraged to re-create their .sdf + files using the latest version of srtm2sdf for the best performance. + +* The loading and display of cartographic boundary files now works + for any region of the planet. + +* A -gpsav command-line switch option was added to instruct SPLAT! to + preserve the temporary working files it creates when invoking gnuplot. + This permits users to view and edit these files, and even re-run + gnuplot outside of SPLAT! (Tnx John McMellen) + +---------------------------------------------------------------------------- + +Release 1.2.2: +By John A. Magliacane (10-May-08): + +* Cleared up some very small inaccuracies (+/- 1 pixel) through better + numerical rounding techniques. + +* Transmitter site location names now appear in .ppm maps even if no + city location files are loaded into SPLAT! + +* Fixed a problem that prevented operation over paths that extended + across the Prime Meridian. + +* Fixed a problem that produced incorrect TX-to-RX distances in the + Site Analysis Report when the -metric switch was used. (Tnx Martin, M0ADY) + +* When generating .ppm map contours, SPLAT! is now slightly more liberal + when loading SDF files to help ensure the contour doesn't get cut off + if it should approach the boundary of an SDF file. + +* Added a new utility called "bearing" (under utils) that determines + distance and azimuth bearings between two site location (.qth) files. + +* The man page installation process was improved. + +* Some very minor documentation updates were made. + +---------------------------------------------------------------------------- + Release 1.2.1: By John A.
