RE: MI Bivariate thematic mapping
have you tried a symbol inside a symbol. I manage to use the same datapoint more than one thematic mapping different columns, loading the layers as many times (more than 3 get dificult to interpret) assigning different symbols at each layer. To the one on the bottom i assign a bigger symbols and as i go up on the layer position i use a smaller symbol could work juanse Chile -Mensaje original- De: Alistair Hart <[EMAIL PROTECTED]> Para: [EMAIL PROTECTED] <[EMAIL PROTECTED]>; [EMAIL PROTECTED] <[EMAIL PROTECTED]> Fecha: Viernes, 31 de Marzo de 2000 01:36 a.m. Asunto: MI Bivariate thematic mapping >Has anyone done bivariate thematic mapping in MapInfo using two different variables succesfully? > >I would like to be able to map a dengue fever outbreak and fill property polygons (regions) with a foreground colour for each mosquito species detected and then change the fill of the same polygons so it varies according to the number of breeding sites on the premise. > >I have successfully managed each operation separately but am having difficulty organising the thematic mapping so that both variables are displayed. > >I already have symbols on the map polygons to indicate other variables so that why I would like to use the polygon fill to state on of the variables. > >Please tell me there is an answer to this! -Maybe an .mbx that takes thematic mapping a little further? hh.. > >TIA >PS: "remember the insect repellent and 'avagoodweekend" > >Alistair Hart >Dengue Action Response Team >Tropical Public Health Unit >Cairns, Australia >[EMAIL PROTECTED] > >-- >To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put >"unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED] -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

RE: MI A Question for Surveyors
Bill In Chile all the hectareage area measured as a projection over the xy plane as an oficial measurement.

RE: MI USGS Geographic Data
Dear Steve and rest of mapper! based on the list it seems that on your countries (especially USA a Australia) there are a bunch of public map data released from some governmental services (USGS, Nasa, Tigger, Zip Codes) that is the start of some of your analysis, or it works like an anchor for modern aerial photographs, satelitte images, or country surveys. Is that declaration true?. Can any of you directme to some of the discution around the point of the property or need of difusion or governmental data (at last paid by all of us)?. In Chile, the paradise for brutal capitalism, all the governmental institutions are going around on how to sell? and how much to charge? for their cartography or any other type of data. As GIS is a new fenomenon here, most of the data or is too expensive, or the institutions haven't decided yet, and they are not releasing their info. I would like to learn what happens or is happening abroad? Any help, comments, will be well received.

MI Street file structure for geocoding
I am amazed of much you know about mapinfo out there in the list. I am a begginer and would be glad to receive some guidance from you. Questions? 1.- when drawing a street map, do you draw just the centerline of each street and give to it the from left, to left, etc atributes, or you draw both sides of each street?. 2.- If only the centerline is needed how do you show this unique line as having two sides, and how do place correctly the pair and odd numbering on either side? 3.- Does it make a difference for the geocoding function of mapinfo if odd numbers go on the right when going to bigger numbering? 4.- How do you deal with street that have diferent lenght (fisicaly and numbering) on both sides?

RE: MI Raster to Vector Conversion
I agree with robert edwards For vectorizing after scanning I am using Streamline 4.0 from Adobe. Usually you still need some hand clening other wise you end up with a lot of non existing object. I been able of only obtaining lines. To get closed polylines of better polygons only work with veru simple drawing. I understand that Corel Draw family have a vectorizing option.
