The Grasshopper Virtual Phone System helps your small business sound more professional and stay connected. When your callers dial your Grasshopper number, they hear a custom main greeting giving them options from which to choose, i.

Assign extensions to each department or employee and let the find-me-follow-me functionality of call forwarding connect callers to the right employees. Give callers access to information such as product information, store hours, or driving directions using Informational Extensions. You can also receive voicemails and faxes online or via email as audio or picture attachments.

With these powerful features available from Grasshopper your small business can stay connected and sound more professional. Our system is designed to enhance your phone service and not to replace it. We only service your incoming calls since the system is virtual and doesn't provide a dial tone.

The extensions of our system are able to forward to your choice of existing numbers such as office, cell, home office, etc. Therefore, you'll also need to have a phone number to be able to receive forwarded calls through our system. This means that you'll need to keep your local service even if at a minimum.

Yes, Grasshopper works in both Canada and the U. Best of all, the minute rate for all calls, incoming or forwarded, is the same in Canada as calls that are made in the U.

No, we offer both month-to-month and annual plans. You can also try our service risk-free with our 7 day free trial. At this time, we provide U. Our plans include multiple extensions that forward callers to any type of phone domestically or internationally. A good portion of Grasshopper's customers are international users.

All of our local numbers accept incoming international calls, but only some countries can call our toll free numbers; it depends on the digits they have to dial for the U.

The International Forwarding feature is included in all plans but turned off by default to avoid fraud and unauthorized use. Your account charges will be deducted from the deposit for the next six months.

We will refund any remaining balance after six months, or if you decide to cancel your account. International calling is only available to customers who've been with Grasshopper for 60 days or more.

If you liked tutorials on this site and do check out spatialthoughts.Understanding the site and topography are crucial first step of any architectural project. Site modelling can become very daunting, expensive, or just cumbersome, often having to use various software to just grasp a general awareness of the site.

I found the most efficient method using QGIS and Rhino Grasshopper to cover most of my analysis, such as contour mapping, wind flow, solar radiation, sun path and shadow, natural topography, and so on.

I also want to control all of these tests parametrically in one software. This is now possible thanks to the wonderful community of Grasshopper who create various plugins.

The second step is gathering topographical data. Satellites make data gathering very simple as the data is made freely available. An architectural project is not just defined within its site boundary. The context is very important. In terms of topography, you would generally require a larger area to perform a proper analysis and understand the surrounding context.

For this larger area, I would use the satellite gathered data. Remote sensing is increasingly becoming more accurate heading towards the true conditions. Therefore, data from satellite scanning could become a very reliable data source for almost anywhere on the earth. Model the site using openly available datasets. My objective is to attain elevation as point values on a grid of 20 and 25 m.

I also want to control the heights of buildings, while also maintain the view for each.

Therefore, at a later stage, I will use an evolutionary solver setting multi-objective optimisation with the height of the building, elevation, and view as constrains. Satellite scanning is increasingly becoming more accurate depending on the site location and could hold valuable information.

They can give a good indication of the surrounding topography and could be at a later stage correlated with more accurate data made from surveying. Alternatively, you might come in possession of a DEM. I also found an alternate method using Heron plugin in grasshopper.

Heron is a wonderful plugin that imports GIS data directly onto Grasshopper without having to go through Method 1. There are plenty of tutorials online on this. The definitions are also available on Heron food4rhino in the examples.Contact your local county Extension office through our County Office List.

Print this fact sheet. Grasshoppers can be the most noticeable and damaging insects to yards and fields. They also are among those most difficult to control, since they are highly mobile. For many reasons, grasshopper populations fluctuate greatly from year to year, and may cause serious damage during periodic outbreaks.

Problems tend to increase beginning in early summer and can persist until hard frosts. Over species of grasshoppers occur in Colorado and their food habits vary.

Some primarily feed on grasses or sedges, while others prefer broadleaved plants. Other grasshoppers restrict their feeding to plants of no great economic value and a few even feed primarily on weed species e.

However, others will readily feed on garden and landscape plants Table 1. Among vegetable crops certain plants are favored, such as lettuce, carrots, beans, sweet corn, and onions. Squash, peas, and tomatoes leaves, not fruit are among the plants that tend to be avoided.

Grasshoppers less commonly feed on leaves of trees and shrubs. However, during outbreak years even these may be damaged. Furthermore, grasshoppers may incidentally damage shelterbelt plantings when they rest on twigs and gnaw on bark, sometimes causing small branches to die back.

All grasshoppers lay their eggs in soil, in the form of tight clustered pods. Relatively dry soils, undisturbed by tillage or irrigations, are preferred. The egg stage is the overwintering stage of most, but not all, grasshoppers. For the majority of species the eggs hatch in mid- to late-spring, varying with soil temperatures. At egg hatch the tiny first stage nymphs move to the surface and seek tender foliage on which to feed.

The first few days are critical to survival. Adverse weather or absence of suitable foods can cause high mortality. Surviving grasshoppers continue to develop over the next several weeks, usually molting through five or six stages, before ultimately reaching the adult form. Adult grasshoppers may live for months, interspersing feeding with mating and egg laying. Species that winter in the egg stage die out in late summer and early fall. A few species, perhaps most conspicuously the speckledwinged grasshopper, spend winter as a nymph, remain active during warm periods, and may develop to the adult form by late winter.

The most important factors are weather related, particularly around the time of egg hatch. For example, cold, wet weather is very destructive to newly hatched grasshoppers.

However, very dry winter and spring conditions also can be harmful to survival since required tender new plant growth is not available.

Some insects commonly feed on grasshoppers. Many species of blister beetles see fact sheet 5. Adult robber flies are common predators of grasshoppers during summer and other flies develop as internal parasites of grasshoppers.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The second photo showed a close look from the upper one. The result was what I want, but I want to get less pointsbut even I set the maximum distance toorthe result was the same. Underdark gave me some advice, and I tried Densify geometries given an interval. First it gave me a polyline shapefile the same as I input, and then I used extract nodes to try to get those points.

But the result was the same as I got using v. The new Python API of the master version 1. There is now a plugin called QChainage that does exactly what you want. You specify an interval distance and the plugin creates points along your line at the specified interval. I've written a script that changes the Sextante Densify geometries tool to accept a certain distance.

It's called Densify geometries given an interval. You can get it from Github and install instructions are on my blog. The chainage will be whatever you set teh sampling interval to be. Well not sure if this is in the stable release, but in the sextante toolbox on 1. Works a treat, be great if it added a field for distance along the line as well though. And with code in general it seems.

I spent a long time struggling with this issue, but eventually got more-or-less what I was looking for using QChainage. What I would like to share is something that may help others.

I have a Points shapefile that overlays this polyline shapefile, I want to break the single polyline shapefile into multiple polylines based on these point locations. I have just done something similar using Arc GIS.

I had a layer of linear features and a fishnet grid that I was using to split the lines, I needed to do this to ascertain the length of the linear features per fishnet polygon.

Add search icon to input field

I did it by intersecting the lines and the fishnet grid. This split the lines where the fishnet crossed them per polygon. I could then dissolve the linear features based upon the fishnet polygon ID field and use a statistic type of SUM to give me the total length of the lines within each polygon.

It gives an option for splitting by reference to other feature class. Split Lines at Points :. Merge all the existing rows so that just one feature represents all the routes Sign up to join this community.

Please RSVP via the meetups page to stay up to date with future events. Over the past decade, he has researched and applied the use of FRP composites to a range of over 30 varied structural applications, from fine art pieces to bridges.

Primary drivers have been the objectives of achieving large scale, high-quality surfaced structures. These have been achieved through radically differing manufacturing approaches.

Significantly, many solutions have arisen out of the conversion of projects, originally conceived of orthodox materials, to FRP. Technical, commercial and industrial interfacing between designer-engineer-constructor-client have required development of approaches unique to the medium. Scope: Design assist, computatational design, shop drawings, visualisation. The masterplan proposal includes a unique and eloquent paving pattern that spans approximately m along Cecil Ave, from Albany Hwy to beyond Pattie Street.

We were provided with the overall surface pattern masterplan, a paving sample drawing and pattern details that identified the paving mixes for each zone. By using computational design tools such as Grasshopper, we were able to extrapolate the information provided to visualise the paving pattern across the entire masterplan.

In addition to refining the overall paving pattern across the site, the custom tool allowed for fine tuning of the paving distributions, with a live feed of quantities for each paving type. An interesting challenge was liaising with the designer, to get inside their mind and try to understand what they are thinking, in order to translate their design intuition, into a series of rules that could be coded. In our initial briefing meeting with PLACE Laboratory, the designer instructed us to distribute the selected paving types randomly.

When you ask the machine to do something randomit is truly randomwhen yourself as a designer tries to do something randomrandom your intuition takes over subconsciously, applying some form of logic to your design. As part of our deliverables, we were asked to deliver detail layout plans and quantities for Lighting Brick, who are contracted to install the pavers.

The grasshopper code allowed for the nominated gap between pavers, with each and every single paver constructed — proving us with an accurate and automated material takeoffs, which would otherwise have been guesswork.

A suite of drawing and layout tools developed in-house was used to automate the production of the drawings, which consisted of 32 detail plans at on A1 Sheets. These drawings will then be used by Lightning Bricks for install. In addition to assisting PLACE Laboratory in design, and providing the shop drawings for install, the detailed 3D model was used to produce accurate visualisations of the final pattern distribution to share with the clients and stakeholders.
