Ziplot-Instant Graphical Elevation Measurement Documentation

Abstract

A system and method of associating elevations with locations on an image map. The image map of a jobsite, e.g., a lot or building. is displayed on an electronic screen on a computer such as a smartphone or smart tablet. A user interface is used to allow a user to locate multiple different markers on different locations of the image map on the electronic screen. A user sets a marker by dragging a cursor to a location. Information is received from an electronic elevation determination device automatically or by manual control. That information represents an elevation of the electronic elevation device at a physical location matching the selected marker on the image map. The elevation information is then automatically associated with and printed beside the selected marker.

Description

BACKGROUND

A common arduous task in construction is documenting job site elevations. This is done for a diverse variety of projects, including engineering, architectural and industrial planning, excavation, grading, foundations, landscaping, septic systems, pools/spas, foundation settlement, remodeling and forensics.

One example is building foundation settlement measurements and documentation often done by home inspectors. Elevations can be taken using a hydrostatic level or hydrostatic altimeter that measures the elevations. This allows the measurer to determine the elevations, and hence determine levels without without the need for line-of-sight.

A house floor plan sketch can be used. Floor elevation deviations can be taken near the corners and center of each room relative to a zero reference elevation, usually established near the center of the home. This hand annotated sketch is usually carried back to an office where its content is typed on a CAD drawing of the house floorplan and provided to the client as part of a home foundation settlement and home inspection report.

Another example is the planning required for a typical building construction project on an empty lot. A sketch of the site is populated with elevation measurements at dots located at property and proposed house corners, along boundary lines, along proposed driveways, sidewalks, boundary lines or other distinctive surface features to plan excavation, grading, slopes, drainage and import or export of soil. Measurements are usually done using an optical level, transit, rotary laser, total station or hydrostatic altimeter. Again, the documented sketch is returned to an office where the measurements are typed on a CAD drawing for incorporation in a site development plan and/or project bid.

Yet another example involves a typical architectural addition or modification to a building. Elevation and distance measurements are hand written on sketches of the existing structure elevation view and the site surface surrounding the structure and taken to the office where the measurements are typed on CAD drawings for planning and bidding the project.

SUMMARY

The present application describes use of an electronic tool to mark locations on an electronic image of an image map, and to automatically associate elevations with those marked locations.

The present application uses a system which allows selecting points on an image map, and serially associating elevations with those points. A cursor is located at the points, and changes in in appearance and/or location once the points are populated with an elevation.

DETAILED DESCRIPTION

FIG. 1 shows an embodiment using an electronic elevation device 100 to automatically obtain elevation readings, and dissociate those elevation readings with points on an image map 120 of the area being imaged. The “computer’ as referred to herein could be a handheld computer, smart device phone, tablet with iOS or Android operating systems or similar processing electronics and operating systems.

The output 105 of the electronic elevation device 100 in FIG. 1 is received by a computer 110 which shows the image map 120 of the area being imaged. In an embodiment, the electronic elevation device can be any elevation measurement instrument such as the ZIPLEVEL PRO-2000 High Precision Altimeter, to record elevation readings. The ZIPLEVEL Pro-2000 is a hydrostatic altimeter device providing an electronic output indicative of elevation relative to a reference or benchmark. However, alternatively, this electronic elevation device 100 could be any device that measures elevation, including an electronic transducer, an electronic rotating laser with an output, a GPS device, which provides altimetry information, or any other precision altimetry device.

The output 105 of the electronic elevation device 100 can be a wired output. In an embodiment, the output of the electronic elevation device 100 is a wireless output such as via Wi-Fi, Bluetooth or any wireless format which provides information indicative of the altimetry reading. In an embodiment, a Bluetooth connection is established between the electronic elevation device 100 and a computer 110.

In an embodiment, the computer 110 may be an android or iOS smartphone or tablet that operates using a processor 115 with conventional computing hardware such as display driver, user interface, and memory. The computer has a screen 111, showing the image map 120. The image map 120 can be any image-based construct that shows the site plan, for example it can be a satellite map, floorplan, CAD drawing, screen shot, photographs, or any other image.

The operation proceeds as shown in FIG. 2. At 200, the user places the cursor 112 at a specific location on the image that matches where they physically want to measure. In operation, the user moves the cursor 112 to a location on the touchscreen. That location of cursor 112 is where the elevation is desired. In an embodiment, this moving is done on a touchscreen based device which is attached to the measurement device. For example, the Android device 110 may be a touchscreen phone in communication with the elevation measuring device 100. They can jointly be secured to a Unipod for ease of measurement.

After setting the location using the cursor, the elevation is automatically or manually recorded at the cursor location at 230.

One embodiment uses flashing cross hairs (shown as cursor 112) dragged by an operator at 200 from a source location 113 on the screen 120 to the location 112 of a desired measurement. Of course, other forms of cursors can also be used.

The cursor is released at 205. This allows a new cursor to appear at the source location 113 for dragging to another location of elevation measurement. In one embodiment, this enables the user to locate a number of different dots in advance of the actual measurement operation. This process of locating additional dots can continue until the user has marked all desired elevation locations on the image map. The process could be carried out in advance of taking all measurements such as in the comfort of a vehicle or office.

In another embodiment, the cursor locating and elevation measuring is done serially, measurement by measurement, on the job site.

At 220, the operator then places the measurement device 100 at a location represented by a flashing cross hair cursor. The user sends the measurement from the measurement device which is received at 230 replacing the flashing cursor with a dot and elevation. The flashing cursor returns to its source location on the touch screen, shown at 210.

In one embodiment, illustrated in FIG. 3, each of the locations which have already been associated with elevation information are shown as solid green dots, such as 300 in FIG. 3. This is also associated with other information shown as 305, which can either be shown all the time, or can be viewed when the cursor is selected. The actual measured elevation 310 is shown adjacent each dot which has been measured. There are a number of spots shown in the FIG. 3 embodiment, which have already been elevation measured.

The hollow cursor shown as 320 in FIG. 3 represents the benchmark zero associated with the value 0.00.

In embodiments, the cursor changes color, shape, size and/or flash rate to indicate that the elevation is being recorded. At this point, an elevation 320 or numerical table label 305 is associated with each of the locations.

This process is repeated at the location of each desired elevation until the touch screen graphic elevations are measured at all desired elevation locations.

The dot edit operation is shown generically at 240. This enables the user to move, remove, or otherwise edit the dot. The dot at any location can be moved by finger contact at any time.

Finger contact on the dot for longer than three seconds without movement can either erase the dot along with any recorded elevation or can bring up an edit screen that rings up a pop-up menu with different options for moving or editing the cursor and hence the location of the dot.

The completed touch screen final form graphic and possible labels and elevation table can immediately be saved and/or shared with clients, coworkers and others.

There are numerous other ways of displaying, locating, moving, saving or deleting elevation locations on a graphic screen or touch screen, and all of these are contemplated to be included within the present system.

The system can use a number of different settings, which can be selected using the controls 130, and are saved until changed. These include:

Scale: IN, inches; FT, feet; CM, centimeters; M, meters

Precision: SP—standard precision (0.05″, 0.005′, 0.1 cm, 0.001 in)

HP—high precision (0.005″. 0.0005′, 0.01 cm, no meters)

Display Sign: Normal—reading increases when Measurement Module is raised for normal ZIPLEVEL use.
