### Tips

 July 2007 - creating territories that respond to different types of constraints Our geographers/consultants are solicited on a regular basis about creating territories that respond to different types of constraints. Lately, innovating answers came up and we naturally thought you would like to know more about them. We combined module of C&D 5.0 to build territories taking into account a certain number of impositions, such as distance and potential. The tool below will allow you to evaluate the potential next to your agencies, subsidiaries, partners or sales teams. In this example, we are looking to evaluate the potential of the 26-50 year-olds in a 10 km perimeter around Tours and Loches (France). The "Poles Selection" module enables the choosing of the places where are settled, for example, the agencies. The module "Qualitative Symbol" allows locating them. The first modules of "Minimum Distance Calculation" and "Filter" (with a base map in output) are there to specify the distance constraint (10 km in this example). In a second phase, the second module of "Minimum Distance Calculation", the second "Filter" (formula: a=a_max) and the module "Value" allow to display the distance between the selected pole(s) and its farthest point. That way, we can use the distance constraints and determine a limit customizable at will. The modules "Surface" and "Calculation" that follow the pole selection allow giving every time the same weight to each point The Polarization (with a qualitative data in output) allows giving every municipality the same quality, given that they are less than 10 km away from the pole Doing this, the module "Fusion" creates a single area on which it is possible to make a sum of the data on the level of the municipality, like the number of 26-50 years-olds ("Aggregation"). All these operations are made on municipalities situated less than 10 km away from the pole. When a municipality is located astride several proximity areas, they are assigned to the nearest pole (as the weights of the polarization are equivalent, only the distance can make the difference). At last, you can display the "value" of the "aggregation" and then modify the constraint on distance (in the first "filter") for it to be more alike the potential threshold first attributed or, - you can compare the potentials on equidistant areas as in our example You can easily reproduce this example using the data sets provided with the software. The base map we used is Indre et Loire by municipalities, the data set "26-50" is a text file named "IndreEtLoire_population99_tranchesAges.txt". Should you have any comment or suggestion about this tip, please contact the technical support by mail (support@articque.com) or by phone (+33 2 47 49 63 21 between 2:00 pm and 6:00 pm from Monday till Thursday, and from 2:00 pm to 5:00 pm on Fridays - CET time) April 2007 - The page setup of the maps with C&D C&D 5.0 "Page setup" function offers many possibilities to move, remove, copy/cut/paste and change properties of every elements on your map before saving it as an image file. To realize these operations, you first need to understand the different ways to select your map's objects on the "Page setup" window. Four different selection tools are available in the toolbar on the top of the Page setup window. The "individual selection" button allows you to choose graphical objects by using the "Control" key on your keyboard and clicking on each object you want to select. The "rectangular selection" button can help you selecting items by drawing a rectangle around the objects. The "circular selection" button can help you selecting items by drawing a circle around the objects. The "free hand selection" button allows you to draw a free area around the objects you want to select. April 2007 - Export your maps in HTML format with C&D HTML export of C&D 5.0 allows you to use your map as a PNG file fixed in a HTML page with a "mapping". "Mapping" is a system of invisible reactive areas drawn in your HTML page over the cities, provinces, territories, etc. of your map. It displays the names and identifiers of your map's objects as a label text when the mouse is over them (1). Hypertext links are pre-programmed on these areas, and they lead to specific page for the clicked area. Label text displaying is made using JavaScript in the source code of your HTML page generated by C&D 5.0. However, if this JavaScript code is accepted by Internet Explorer 7, it can't be recognized by Mozilla FireFox. To make this label text function working under Mozilla FireFox, you need to replace a part of the source code after the and between the tags of your HTML page by : ```var isNav=(navigator.appName.indexOf('Mozilla')!=-1); var isWin=(navigator.platform.indexOf('Win')!=-1); var xpos,ypos; window.onload = init; function init() {if (window.Event) {document.captureEvents(Event.MOUSEMOVE);}document.onmousemove = getXY;} function getXY(e) {xpos = (window.Event) ? e.pageX : event.clientX;ypos = (window.Event) ? e.pageY : event.clientY;} function show_hide_layer(command) {var obj;if (!isNav) obj=idlayer; else obj=document.idlayer; if (obj!=null) { if (obj.style) { obj=obj.style; command=(command=='show')?'visible':(command='hide')?'hidden':command; } if (isWin || isNav) { obj.left=xpos+30; obj.top=ypos-30; } obj.visibility=command; } } function showid(value) { var obj; htmlval=""+"
"+value+"
