This is very much like what I have described elsewhere on this server for the production of MPEGs from Arc/Info coverages.
Essentially you just do a series of SCREENSAVEs, and find some way to string the images together. The nitty-gritty Arc/Info stuff is:
display 9999 size canvase 150 200That way I have standard-sized images.
&args bdate bframe numframe /* animation.aml Written by Erich Schroeder, Illinois State Museum /* sometime in late 1995, greatly modified for different purposes.. /* /* The goal of this aml is just to do a series of screensaves to create /* some frames to be animated in some way. The arguments are: /* bdate = begining date for this part of the animation. /* bframe = beginning frame number for this part of the animation /* (note: not really used much in this incarnation of the aml) /* numframe = the number of iterations (frames) to be produced in this run. /* /* I run this in grouping of about 20 or so. The land records data set is /* large (over 500,000 90-byte records) so it ties up the machine pretty well. /* /* First, set up two relations called "mm" and "max" to use. /* "mm" is the basic relation to tie the coverage and the info file together. /* "max" helps in identifying sections that are completely in private /* ownership by the year in question. relate add mm statepur info trs trs ordered auto max maxyear info trs trs ordered auto ~ /* /* Set up an ending point... /* &s eframe = %bframe% + %numframe% /* /* standard arcplot stuff /* shadeset color mape /illinois/admin/county-nl mapposition cen cen /* /* Make a map for one year...save it...and loop around. /* &do i = %bframe% &to %eframe% &by 1 clear arcs /illinois/admin/state-nl move 0.05 0.15 textsize .1 text %bdate% clearselect reselect state2 poly max//year lt %bdate% polygonshades state2 2 nselect state2 poly reselect state2 poly mm//year eq %bdate% polygonshades state2 7 &type done with %bdate%, frame %i% screensave pur%bdate%.ras &s bdate = %bdate% + 1 &end &type final values==== bdate, %bdate%, frame %i% &return
