The Lafayette Consolidated Government implemented a Mosquito Abatement program in the summer of 2001 in direct response to the threat of the West Nile virus. The program was given a boost when that June a tropical storm dropped up to 30 inches of rain in the area. FEMA provided additional funding that year as a consequence of the tropical storm manifesting a large mosquito population.
Shortly thereafter the LCG Council foresaw the ongoing need for a fully funded Mosquito Abatement program for Lafayette Parish. A tax proposition was placed on the ballot in an election in the summer of 2002. It passed.
With the necessary funding in place, LCG has implemented a Mosquito Abatement Plan, which includes the GPS tracking of all Mosquito Spray units as they perform their service. This tracking allows LCG the oversight of the Contractor’s day-to-day operation to help ensure that the contract is fulfilled.
LCG has decided to publish these daily GPS spray trails on the Internet to allow the Public and concerned citizens to view and answer the questions: “Have I been sprayed?” and “When was the last time?”
The Daily Mosquito Spray Map will be updated each Monday - Friday that mosquito spraying has occurred since the last update. The spraying may not occur when the wind exceeds a certain speed, it is raining, threatening rain or the temperature drops below a certain value. The spraying generally occurs during the early morning and early evening hours. No spraying occurs on weekends, unless certain conditions warrant. Any weekend spraying will be updated on the following Monday.
How To Use
Click on the Daily Mosquito Spray Map link in the GIS MENU sidebar. An Interactive Map page will display. A Progression indicator floats atop the map area to show that the server is working by displaying a black banner labeled “Retrieving map”. Any time this banner is visible do not click on the map until the map image retrieval is finished (Length of time is dependent upon connection speed and server load).
Notice on the left frame there is a set of tools on a toolbar. The currently selected tool is identified by a red outline box. Any time you click on the map area the function of the currently selected tool will be carried out. If you hover your mouse pointer over each tool’s Icon, a pop up label will tell you what the tool does.
This Interactive Map is designed for the user to type in an Address (must be a valid House number and street name) or two intersecting streets and click on the Locate button. The map will auto zoom to that Address area.
If that Address has been sprayed in the current month you will observe small colored squares, which represent GPS points along the street centerlines. There are labels on some of the points, which tell the speed of the mosquito spray unit as it has passed near the Address. Every few points are further labeled with a Date, Speed and Spray Unit ID at that GPS point.
If you want detailed information on any point, whether labeled or not, click the red “i” information Icon on the toolbar. Notice the Identify icon becomes surrounded by a red outline box (becomes the selected tool). Click on any square point and observe that an attribute table appears in the bottom frame with a table of detailed information about the point. Other tables display information about the other layers on the map. You can view all of them by scrolling up or down in the bottom frame.
If there are no Squares near the Address then there has been no Mosquito Spraying Activity near this area in the current month. If you wish to know if and when the Address had been sprayed in previous months, you must toggle the Legend to the Layer List. To do so, hover your mouse over the upper leftmost toolbar icon and see it display “Toggle between Legend and Layer list”. Click this Icon and observe the rightmost frame now displays a Layer list, which have Check boxes next to all available layers.
Check the box (Click on the Checkbox) next to any and/or all layers you wish to display or uncheck any box associated with a layer, which you do not wish to display. Once the layers are Checked or Unchecked click the Refresh Map button for the changes to take effect. Allow the Progression bar to go away before clicking on the map. Once layers are selected you may Toggle back to the Legend list by clicking the previously mentioned Icon.
Note: The more layers you Check to display, the slower will be the retrieval of the map image, therefore if you are on a slow connection you may want to limit your layer display to as few as possible to maximize your response time. The same holds true for zooming out, as each turned on layer has to be processed over a larger and larger area as you zoom out.
If you find your computer not responding fast enough or you’ve waited as long as you are willing, click on the Interactive Maps upper right “CLOSE” box to close the Map and place you back at the GIS MENU page. OR, once you have finished using the Interactive Map, you end your session by clicking the “CLOSE” box.
Do not use your browsers “BACK” page or arrow to get back to the GIS MENU. The interactive Map Server does not allow the normal function of these back functions and will only cause the map to un-draw and display unexpected results. Click the “CLOSE” box, or click the "Back" link (See Below) in the Left Tool bar Frame. Re-launch the Interactive Map from the GIS MENU page to begin again.
